MLENV
This feature is not supported on the Wolfram Cloud.

has been replaced by WSENV.


is a MathLink type representing a MathLink library environment.

DetailsDetails

  • The MathLink environment object stores the global state of MathLink during the execution of a program.
  • MLENV is defined in the file mathlink.h, which should be included in the source code for any MathLink-compatible program.
  • MLENV objects are created by the MLInitialize() function and deallocated by the MLDeinitialize() function.
  • Each MathLink program must create a MLENV object before accessing any other MathLink functionality.
  • MLENV is declared in the MathLink header file mathlink.h.
