Wraps the standard POSIX `kill()` function.
|
|
|
|
`sig` may be any supported POSIX signal, including values such as `SIGTERM`, `SIGKILL`, `SIGINT`, `SIGUSR1`, `SIGUSR2`, `SIGCHLD`, `SIGCONT`, and related process-control signals.
|
|
|
|
Passing `0` as the signal performs an existence and permission check without actually delivering a signal.
