MLInitialize has been replaced by WSInitialize.

initializes the MathLink environment object and passes parameters in p.


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