| ## E.4 libSingular `libSingular` is the C++-library version of SINGULAR. `Singular/libsingular.h` is the main include file, `-lSingular` the link parameter, `lib/pkgconfig/Singular.pc` provides all parameters in the pkconfig format. It contains all parts of SINGULAR with the following exceptions: memory allocation functions for GMP (see `mmInit` in `Singular/tesths.cc`) signal handlers (see `init_signals` in `Singular/cntrlc.cc`). At least a handler for `SIGCHLD` must be installed for the commands waitfirst, waitall and the routines from parallel_lib, modstd_lib, normal_lib, tasks_lib. If the child was started by `libSingular` the handler has to call `sig_chld_hdl` from `Singular/links/ssiLink.cc` or implement something similar (call `slClose(l)` for ssi links). error handlers for factory, NTL (see `init_signals` in `Singular/cntrlc.cc`). parallelism: The number of cores defaults to 1 ( Parallel computing)
