Function Documentation

pidfile()

int pidfile

(

const char *

basename

)

Create or update mtime of process PID file.

Parameters

basename

Program name, or NULL, may start with '/'

This function is intended to be used by UNIX daemons to save the PID of the main process responsible for handling signals. If basename is NULL the implicit __progname variable from the C-library is used. The basename may also start with '/', in which case it is interpreted as the absolute path to the PID file.

Returns

POSIX OK(0) on success, otherwise non-zero on error.
