NAME
posix_spawnattr_setsigdefault
posix_spawnattr_getsigdefault —
set or get the
spawn-sigdefault
attribute on a posix_spawnattr_t
SYNOPSIS
#include
<spawn.h>
int
posix_spawnattr_setsigdefault(posix_spawnattr_t
*restrict attr, const sigset_t *restrict
sigdefault);
int
posix_spawnattr_getsigdefault(const
posix_spawnattr_t *restrict attr, sigset_t *restrict
sigdefault);
DESCRIPTION
The
posix_spawnattr_setsigdefault()
function sets the sigdefault on the attributes object
referenced by attr.
The
posix_spawnattr_getsigdefault()
function retrieves the sigdefault on the attributes
object referenced by attr.
The argument sigdefault is the set of signals to be returned to default behaviour in the new process on creation if the POSIX_SPAWN_SETSIGDEF flag is set in the posix_spawnattr_t. It's default value must be set via a call to posix_spawnattr_setflags(3) or the behaviour is undefined.
RETURN VALUES
On success, these functions return 0; on failure they return an
error number from <errno.h>.
Additionally, if successful,
posix_spawnattr_getsigdefault() will modify the
contents of the sigdefault parameter with the current
attribute value.
ERRORS
These functions may fail if:
- [
EINVAL] - The value specified by attr is invalid.
- [
EINVAL] - The value of attr is invalid.
