WSPutUTF16String()
This feature is not supported on the Wolfram Cloud.

int WSPutUTF16String(WSLINK link,const unsigned short *s,int len)
puts a UTF-16 string s of length len to the WSTP connection specified by link.

DetailsDetails

  • WSPutUTF16String() determines the number of characters in the string s automatically.
  • The string s encoded in the UTF-16 encoding form must start with a byte order mark.
  • The string length len must include the byte order mark.
  • WSPutUTF16String() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use WSError() to retrieve the error code if WSPutUTF16String() fails.
  • WSPutUTF16String() is declared in the WSTP header file wstp.h.
