MathLink C Function

MLVersionNumbers()

void MLVersionNumbers(MLENV ep, int *inumb, int *rnumb, int *bnumb)
returns the MathLink API interface number, revision number, and build number and stores them respectively in inumb, rnumb, and bnumb.
  • For computer systems where the MathLink libraries are distributed as dynamic library modules, MLVersionNumbers() allows a runtime inspection of the version information for the MathLink library.
  • MLVersionNumbers() will also function for programs that use the MathLink library statically; however, the function return values will not change.
  • MLVersionNumbers() is declared in the MathLink header file mathlink.h.
