WSPutRealNumberAsUTF16String()
This feature is not supported on the Wolfram Cloud.

int WSPutRealNumberAsUTF16String(WSLINK l, const unsigned short *s, int n)
sends a floating-point number encoded as UTF-16 string s of length n to the WSTP connection specified by l.

DetailsDetails

  • Send the number s in the form "3.14159".
  • The number s encoded in UTF-16 must begin with a byte order mark.
  • The length of the string n must include the byte order mark.
  • WSPutRealNumberAsUTF16String() returns 0 on error, and a nonzero value if the function succeeds.
  • WSPutRealNumberAsUTF16String() is declared in the WSTP header file wstp.h.
