accept_socket

Version 2.11

`accept_socket`

#include "sflsock.h"
sock_t
accept_socket (
    sock_t master_socket)

Synopsis

Accepts a connection on a specified master socket. If you do not want to wait on this call, use select() to poll the socket until there is an incoming request, then call accept_socket. Returns the number of the new slave socket, or INVALID_SOCKET if there was an error on the accept call. You can handle errors as fatal except for EAGAIN which indicates that the operation would cause a non-blocking socket to block (treat EWOULDBLOCK in the same way).
