WSPutUCS2Function()
This feature is not supported on the Wolfram Cloud.

int WSPutUCS2Function((WSLINK l, const unsigned short *s, int v, int n)
puts a function with head given by a UCS2 encoded symbol with name s of length v and with n arguments to the WSTP connection specified by l.

DetailsDetails

  • After the call to WSPutUCS2Function(), other WSTP functions must be called to send the arguments of the function.
  • WSPutUCS2Function() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use WSError() to retrieve the error code if WSPutUCS2Function() fails.
  • WSPutUCS2Function() is declared in the WSTP header file wstp.h.
