POSIX_SPAWNATTR_GETFLAGS(3) FreeBSD Library Functions Manual
NAME
posix_spawnattr_getflags, posix_spawnattr_setflags - get or set flags of
a posix_spawn attributes object
SYNOPSIS
#include <spawn.h>
int
posix_spawnattr_getflags(const posix_spawnattr_t *restrict attr,
short *restrict flags);
int
posix_spawnattr_setflags(posix_spawnattr_t *attr, short flags);
DESCRIPTION
The posix_spawnattr_getflags() and posix_spawnattr_setflags() functions
are used to get or set the flags part of a posix_spawn(3) attribute
object referenced by attr.
Flag values are OR-ed from the following flags:
POSIX_SPAWN_RESETIDS
Reset the effective user and group ID of the child process
to the parent's real user and group ID; see setegid(2).
If the new process is created from a set-user-ID or set-
group-ID file, usual execve(2) semantics take precedence.
POSIX_SPAWN_SETPGROUP
Set the process group of the child process according to the
pgroup attribute of the object; see
posix_spawnattr_getpgroup(3) and setpgid(2).
POSIX_SPAWN_SETSIGDEF
Reset signals set by posix_spawnattr_setsigdefault(3) to
their default value in the child process.
POSIX_SPAWN_SETSIGMASK
Set the signal mask of the child process according to the
value set by posix_spawnattr_setsigmask(3), using
sigprocmask(2).
POSIX_SPAWN_SETSCHEDPARAM
Set the scheduling parameter of the child process according
to the value set by posix_spawnattr_setschedparam(3)
(mandated by IEEE Std 1003.1-2001 ("POSIX.1"), this
implementation currently does nothing).
POSIX_SPAWN_SETSCHEDULER
Set the scheduler policy of the child process according to
the value set by posix_spawnattr_setschedpolicy(3) (mandated
by IEEE Std 1003.1-2001 ("POSIX.1"), this implementation
currently does nothing).
posix_spawnattr_init(3) initializes this value to no flags set.
RETURN VALUES
Both functions return 0.
