## Macro Definition Documentation

#define DBL_NAN

User-definable macro that represents a portable double floating point NaN value (defined by default to a platform-specific NaN value)

#define DBL_NINFTY

User-definable macro that represents a portable double floating point negative infinite value (defined by default to a platform-specific value)

#define DBL_PINFTY

User-definable macro that represents a portable double floating point positive infinite value (defined by default to a platform-specific value)

#define FLT_NAN

User-definable macro that represents a portable single floating point NaN value (defined by default to a platform-specific NaN value)

#define FLT_NINFTY

User-definable macro that represents a portable single floating point negative infinite value (defined by default to a platform-specific value)

#define FLT_PINFTY

User-definable macro that represents a portable single floating point positive infinite value (defined by default to a platform-specific value)

#define LONG64 int64_t

User-definable macro that represents a portable signed 64 bit integer type.

Legacy platforms that do not support 64 bit types can still be used by redefining `LONG64` to `int`. For example:

    cc -D LONG64=int -D ULONG64="unsigned int" -D SOAP_LONG_FORMAT='"%d"' -D SOAP_ULONG_FORMAT='"%u"' -o client stdsoap2.c soapC.c soapClient.c client.c

This type is also available as a valid type to use in the .h file for soapcpp2.

See also
  `ULONG64`, `SOAP_LONG_FORMAT`, `SOAP_ULONG_FORMAT`.

#define SOAP_BUFLEN (65536)

User-definable size of the input and output message buffer `soap::buf` (the value is 65536 by default)

This macro defines the size of the input and output message buffer, which is 65536 by default unless the `WITH_LEAN` or `WITH_LEANER` compile-time flags are used and the buffer size is 2048. The size of the buffer affects the performance of socket communications, with larger sizes above 8192 generally improving the performance at the cost of the extra memory required to store the larger `soap` context.

A default value of 65535 was chosen for OpenVMS TCP/IP stacks that cannot handle 65536 bytes. A default value of 2048 is used for WinCE platforms. A default value of 32767 is used for Tandom NonStop platforms.

Warning
  When the value of this macro is assigned at the compiler's command line or in an IDE or by specifying `SOAPDEFS_H`, then all source code files of an application's project must be recompiled. Otherwise, `soap` context corruption errors may occur in the non-recompiled parts of the application, because the size of the `soap` context has changed.

SOAP_FMAC3 int SOAP_FMAC4 soap_put_int(struct soap *soap, const int *ptr, const char *tag, const char *type);
SOAP_FMAC3 int * SOAP_FMAC4 soap_get_int(struct soap *soap, int *ptr, const char *tag, const char *type);

Other serialization functions are generated as well, either as C++ inlines or C defines.

See also

The soapcpp2 tool generates service functions as follows at the client and service sides, respectively:

SOAP_FMAC5 int SOAP_FMAC6 soap_call_ns__webmethod(struct soap *soap, ...) { ... }
SOAP_FMAC5 int SOAP_FMAC6 soap_serve_ns__webmethod(struct soap *soap)

User-definable macro to override free() for unmanaged heap allocation.

#define SOAP_HDRLEN (8192)

User-definable maximum length of HTTP headers (the value is 8192 by default)

Warning
  When the value of this macro is assigned at the compiler's command line or in an IDE or by specifying `SOAPDEFS_H`, then all source code files of an application's project must be recompiled. Otherwise, `soap` context corruption errors may occur in the non-recompiled parts of the application, because the size of the `soap` context has changed.

#define SOAP_INVALID_SOCKET (-1)

Macro that defines a portable invalid socket value (usually -1, but the value depends on the OS)

This macro is "%lld" or "%I64d" on Windows.

#define SOAP_MALLOC | ( |  | soap,
|  |  | size
| ) |  | malloc((size))

User-definable macro to override malloc() for context-managed heap allocation (excluding C++ class instances, see `SOAP_NEW`)

#define SOAP_MALLOC_UNMANAGED | ( |  | soap,
|  |  | size
| ) |  | malloc((size))

User-definable macro to override malloc() for unmanaged heap allocation.

#define SOAP_MAXALLOCSIZE (0)

User-definable maximum size of a block of memory that `malloc` can allocate or 0 for no limit (the value is 0 by default)

#define SOAP_MAXARRAYSIZE (100000)

User-definable macro to protect excessive SOAP array allocation requests by defining a maximum allocation threshold.

Deserialized SOAP arrays larger in size than `SOAP_MAXARRAYSIZE` are not pre-allocated in memory, but deserialized on an element-by-element basis until XML validation contrains kick in (the value is 100000 by default)

#define SOAP_MAXDIMESIZE (8*1048576)

User-definable maximum length of DIME attachments received (the value is 8 MB by default)

DIME attachments sizes are limited to `SOAP_MAXDIMESIZE`. Increase this value to allow larger attachments or decrease when resources are limited, this limit is to deny senders to pre-allocate excessive memory at the receiver side without actually sending the whole message, i.e. this threshold protects against DIME-based memory resource usage attacks.

#define SOAP_MAXEINTR (10)

User-definable maximum number of EINTR interrupts to ignore while polling a socket for pending activity, each EINTR ignored may increase the I/O blocking time by at most one second (the value is 10 by default)

User-definable maximum HTTP chunk size receivable (the value is 2147483647 by default), also HTTP chunk sizes cannot exceed `soap::recv_maxlength`.

#define SOAP_MAXINFLATESIZE (1*1048576)

Trusted inflated content size (1 MB by default), larger content is subject to the `SOAP_MINDEFLATERATIO` constraint, i.e. if `SOAP_MINDEFLATERATIO` is 1.0, `SOAP_MAXINFLATESIZE` is always the max size of uncompressed content.

#define SOAP_MAXKEEPALIVE (100)

User-definable maximum iterations in the server-side `soap_serve` loop (or the C++ service class `serve` method) on HTTP keep-alive connections, assigned to `soap::max_keep_alive` which can be altered at runtime (the value is 100 by default)

#define SOAP_MAXLENGTH (0)

User-definable maximum string content length for strings not already constrained by XML schema validation constraints, zero or negative means unlimited string lengths are allowed (the value is 0 by default)

#define SOAP_MAXLEVEL (10000)

User-definable maximum XML nesting depth level permitted by the XML parser, must be greater than zero (the value is 10000 by default)

#define SOAP_MAXOCCURS (100000)

User-definable maximum number of array or container elements for containers that are not already constrained by XML schema validation constraints, must be greater than zero (the value is 100000 by default)

#define SOAP_MINDEFLATERATIO (1.0/1032.0)

Trusted deflation ratio after `SOAP_MAXINFLATESIZE` is reached, trust when compressed / deflated > `SOAP_MINDEFLATERATIO` (default is 0.00096899224806 or 1032:1, which is according to the zlib site: "The limit (1032:1) comes from the fact that one length/distance pair can represent at most 258 output bytes. A length requires at least one bit and a distance requires at least one bit, so two bits in can give 258 bytes out, or eight bits in give 1032 bytes out. A dynamic block has no length restriction, so you could get arbitrarily close to the limit of 1032:1.".

#define SOAP_NEW | ( |  | soap,
|  |  | type
| ) |  | new SOAP_NOTHROW (type)

User-definable macro to override C++ new.

#define SOAP_NEW_ARRAY | ( |  | soap,
|  |  | type,
|  |  | n
| ) |  | new SOAP_NOTHROW type[n]

User-definable macro to override C++ new for arrays.

#define SOAP_NEW_UNMANAGED | ( |  | soap | ) | new SOAP_NOTHROW soap

User-definable macro to override C++ new for unmanaged allocation of the soap context.

#define SOAP_NMAC

User-definable macro to annotate namespace table definitions.

The soapcpp2 tool generates `Namespace` tables with XML namespace bindings which are declared as follows:

SOAP_NMAC struct Namespace namespaces[] = { ... };

#define SOAP_NOTHROW (std::nothrow)

Macro expands to `(std::nothrow)` to prevent the deserializer's memory allocator from throwing an exception but return `SOAP_EOM` instead, this macro is empty when `WITH_COMPAT` is enabled or when `WITH_LEAN` or `WITH_LEANER` are enabled which means that exceptions may be thrown.

It is possible to enable C++ exceptions without detrimental effects by compiling the source code with `SOAP_NOTHROW` set to an empty value and in that case C++ exception handlers should be used to catch `std::bad_alloc`.

By default, `soap_new` and the soapcpp2-generated `soap_new_T` functions return NULL when allocation failed.

Warning
  `soap_malloc` never throws `std::bad_alloc`, which means that parsing and deserialization of C++ data may not throw `std::bad_alloc` in some cases, but rather the functions called will return `SOAP_EOM` and `soap::error` is set to `SOAP_EOM`. `soap_malloc` also returns `SOAP_EOM` when `SOAP_MAXALLOCSIZE` is exceeded.

Example:

      c++ -D SOAP_NOTHROW="" -o client stdsoap2.cpp soapC.cpp soapClient.cpp client.cpp

  // compiled with compile-time flag -D SOAP_NOTHROW=""
  #include "soapH.h"
  try
  {
  // soap_new() may cause a std::bad_alloc exception
  struct soap *soap = soap_new();
  // MyClass is declared in soapH.h generated by soapcpp2 from a .h file with MyClass
  MyClass *obj = soap_new_MyClass(soap);
  ... // use obj
  }
  catch (std::bad_alloc)
  {
  ... // out of memory error
  }

#define SOAP_PLACEMENT_NEW | ( |  | soap,
|  |  | buf,
|  |  | type
| ) |  | new (buf) (type)

User-definable macro to override C++ placement new.

#define SOAP_PURE_VIRTUAL = 0

Macro is set to `SOAP_PURE_VIRTUAL` = 0 at compile time when macro `WITH_PURE_VIRTUAL` is defined.

#define SOAP_SOCKET int

Macro that defines a portable socket type, usually `int`, but the type may depend on the platform being used.

#define SOAP_SOCKLEN_T size_t

Macro that defines a portable socklen_t type (usually `size_t`, but type depends on the OS)

#define SOAP_SSL_RSA_BITS (2048)

User-definable length of RSA keys used for https connections (the value is 2048 by default), ignored with OpenSSL v3.

#define SOAP_STD_EXPORTS

User-definable macro to enable Windows DLL builds.

This macro when set exports global functions and classes by defining `SOAP_FMAC1`, `SOAP_FMAC3`, `SOAP_FMAC5`, and `SOAP_CMAC` to `__declspec(dllexport)`.

Example:

      C:> soapcpp2.exe -penv env.h
      C:> cl /c /I. /EHsc /DWITH_NONAMESPACES /DSOAP_STD_EXPORTS envC.cpp stdsoap2.cpp
      C:> link /LIBPATH ws2_32.lib /OUT:mygsoap.dll /DLL envC.obj stdsoap2.obj

#define SOAP_TAGLEN (1024)

User-definable maximum length of XML tags and URLs (the value is 1024 by default)

Warning
  When the value of this macro is assigned at the compiler's command line or in an IDE or by specifying `SOAPDEFS_H`, then all source code files of an application's project must be recompiled. Otherwise, `soap` context corruption errors may occur in the non-recompiled parts of the application, because the size of the `soap` context has changed.

#define SOAP_TMPLEN (1024)

User-definable maximum length of temporary string values stored in `soap::msgbuf` and `soap::tmpbuf`, e.g. to hold short strings and brief error messages (1024 by default, must not be less than 1024)

Warning
  When the value of this macro is assigned at the compiler's command line or in an IDE or by specifying `SOAPDEFS_H`, then all source code files of an application's project must be recompiled. Otherwise, `soap` context corruption errors may occur in the non-recompiled parts of the application, because the size of the `soap` context has changed.

#define SOAP_ULONG_FORMAT "%llu"

User-definable macro that represents the `ULONG64` printf %-format.

This macro is "%llu" or "%I64u" on Windows.

#define SOAP_UNKNOWN_CHAR (0x7F)

#define SOAP_UNKNOWN_UNICODE_CHAR (0xFFFD)

A user-definable integer Unicode value representing a character that replaces an invalid Unicode code point, i.e. when converting an XML invalid Unicode character from UTF-8 (the value is 0xFFFD by default)

#define soap_valid_socket | ( |  | sock | ) | ((sock) != SOAP_INVALID_SOCKET)

Function macro to check if a socket is valid, i.e. not equal to `SOAP_INVALID_SOCKET`

#define ULONG64 uint64_t

User-definable macro that represents a portable unsigned 64 bit integer type.

Legacy platforms that do not support 64 bit types can still be used by redefining `LONG64` to `int`. For example:

    cc -D LONG64=int -D ULONG64="unsigned int" -D SOAP_LONG_FORMAT='"%d"' -D SOAP_ULONG_FORMAT='"%u"' -o client stdsoap2.c soapC.c soapClient.c client.c

This type is also available as a valid type to use in the .h file for soapcpp2.
