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

int WSFlush(WSLINK link)
flushes out any buffers containing data waiting to be sent on link.

DetailsDetails

  • If you call WSNextPacket() or any of the WSGet functions, then WSFlush() will be called automatically.
  • If you call WSReady(), then you need to call WSFlush() first in order to ensure that any necessary outgoing data has been sent.
  • WSFlush() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use WSError() to retrieve the error code if WSFlush() fails.
  • WSFlush() is declared in the WSTP header file wstp.h.
