WSENV
This feature is not supported on the Wolfram Cloud.


is a WSTP type representing a WSTP library environment.

DetailsDetails

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