int WSPutReal64(WSLINK link,double x)
puts the double-precision floating-point number x to the WSTP connection specified by link.


  • WSPutReal64() returns 0 in the event of an error, and a nonzero value otherwise.
  • Use WSError() to retrieve the error code if WSPutReal64() fails.
  • WSPutReal64() is declared in the WSTP header file wstp.h.
