SysSock2Accept
(FUN)
FUNCTION SysSock2Accept : RTS_IEC_HANDLE
Accept the next incoming TCP connection.
This functions calls the function accept of the operating system, which can accept a request to connect
to a socket. A new descriptor (handle) for the socket is returned. The original socket is reset to the
“listening” state (see SysSockListen).
Note
For TLS Sockets the blocking mode will be set to nonblocking for the new client sockets. If a blocking behavior is needed use SysSock2Ioctl to set the socket to blocking mode. This reflects the behavior of SysSock2Create for TLS sockets.
