fcntl() call z/OS Communications Server: IP CICS Sockets Guide SC27-3649-00 |
|
The fcntl() call controls whether a socket is in blocking or nonblocking mode. The blocking or nonblocking mode of a socket affects the operation of certain commands. In blocking mode, a call waits for certain events until they happen. When this happens, the operating system suspends the program until the event occurs. In similar situations with nonblocking calls, the call returns an error return code and the program continues. |
