SIGCONT
Encyclopedia : S : SI : SIG : SIGCONT
On POSIX compliant platforms, SIGCONT is the symbolic name for the signal sent to restart a computer program previously paused by the SIGSTOP signal. SIGCONT is a symbolic constant defined in signal.h. Symbolic signal names are used as signal numbers can vary across platforms.
Etymology
SIG- is a common prefix for signal names. CONT is an abbreviation for continue.Usage
When SIGSTOP is sent to a process, the usual behaviour is to pause that process in its current state. The process will only resume execution if it is sent the SIGCONT signal. SIGSTOP and SIGCONT are used for job control in the Unix shell, among other purposes.
