int WSPutUTF16Symbol(WSLINK link,const unsigned short *s,int len)

puts a symbol whose name is given by UTF-16 encoded string s with length len to the WSTP connection specified by link.

Details

  • The symbol must be encoded in the UTF-16 character encoding form.
  • The symbol s must start with a byte order mark.
  • The length of the symbol len must include the byte order mark.
  • WSPutUTF16Symbol() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use WSError() to retrieve the error code if WSPutUTF16Symbol() fails.
  • WSPutUTF16Symbol() is declared in the WSTP header file wstp.h.
