WSInitialize (C Function)

WSENV WSInitialize(WSEnvironmentParameter p)

initializes the WSTP environment object and passes parameters in p.

Details

  • The WSTP environment object stores the global state of WSTP during the execution of a program.
  • A program can install custom memory allocators using the environment parameters object p.
  • An appropriate call to WSInitialize() is generated automatically when an external program is created from WSTP templates.
  • Any external program that uses the WSTP library must call WSInitialize() before calling any other link-related WSTP library functions.
  • The WSTP environment functions as a factory to create link objects.
  • WSInitialize() is declared in the WSTP header file wstp.h.
