WSPutUTF16Function (C Function)

int WSPutUTF16Function(( WSLINK l , const unsigned short * s , int v , int n )

puts a function with head given by a UTF-16 encoded symbol with name s of length v and with n arguments to the WSTP connection specified by l.

Details

  • After the call to WSPutUTF16Function(), other WSTP functions must be called to send the arguments of the function.
  • The function name s encoded in UTF-16 must start with a byte order mark.
  • The length of the symbol name s must include the byte order mark.
  • WSPutUTF16Function() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use WSError() to retrieve the error code if WSPutUTF16Function() fails.
  • WSPutUTF16Function() is declared in the WSTP header file wstp.h.
