int WSPutInteger8((WSLINK l, unsigned char i)
puts the 8-bit integer i to the WSTP connection specified by l.


  • WSPutInteger8() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use WSError() to retrieve the error code if WSPutInteger8() fails.
  • WSPutInteger8() is declared in the WSTP header file wstp.h.
