Function
GLibfdwalk_set_cloexec
since: 2.80
Declaration [src]
int
g_fdwalk_set_cloexec (
int lowfd
)
Description [src]
Mark every file descriptor equal to or greater than lowfd to be closed
at the next execve() or similar, as if via the FD_CLOEXEC flag.
Typically lowfd will be 3, to leave standard input, standard output
and standard error open after exec.
This is the same as Linux close_range (lowfd, ~0U, CLOSE_RANGE_CLOEXEC),
but portable to other OSs and to older versions of Linux.
This function is async-signal safe, making it safe to call from a
signal handler or a GSpawnChildSetupFunc, as long as lowfd is
non-negative.
See signal(7) and
signal-safety(7) for more details.
Available since: 2.80
