12.3.42 SP_initialize() [macro]

Synopsis

     #include <sicstus/sicstus.h>
     
     int
     SP_initialize(int argc,
     	      char **argv,
     	      void *reserved);

Initializes the Prolog engine.

Arguments

argc

The number of elements of the argv vector.

argv

A vector of strings that can be accessed by prolog_flag(argv,X).

reserved

Should be NULL

Return Value

SP_SUCCESS if initialization was successful. If initialization was successful, further calls to SP_initialize() will be no-ops (and return SP_SUCCESS).

Description

This must be done before any interface functions are called, except those annotated as [preinit]. The function will allocate data areas used by Prolog, initialize command line arguments so that they can be accessed by the argv Prolog flag, and load the Runtime Library.
