This feature is not supported on the Wolfram Cloud.

int WSPutArgCount(WSLINK link,int n)
specifies the number of arguments of a composite function to be put on link.

DetailsDetails

  • WSPutArgCount() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use WSError() to retrieve the error code if WSPutArgCount() fails.
  • WSPutArgCount() is declared in the WSTP header file wstp.h.
