status = %SS_SENDBUF(socket, buf)
Return value
status
Returns SS_SUCCESS (0) or one of the errors in Error codes returned by %SS_SENDBUF below. (n)
Arguments
socket
A descriptor of an open socket created by %SS_SOCKET. (i4)
buf
Buffer containing the data to be sent. (a)
Discussion
%SS_SENDBUF writes outgoing data through a connected stream socket in a loop to ensure the entire data packet is delivered. %SS_SENDBUF is equivalent to calling %SS_SEND in a loop.
If no buffer space is available within the transport system to hold the data to be transmitted, or if %SS_SENDBUF hasn’t finished sending all the data, %SS_SENDBUF blocks.
%SS_RECVBUF is the complimentary function used in a peer Synergy DBL socket application.
