POSIX_SPAWNATTR_GETFL... BSD Library Functions Manual POSIX_SPAWNATTR_GETFL...NAME
posix_spawnattr_getflags, posix_spawnattr_setflags — get and set the
spawn-flags attribute of a spawn attributes object
LIBRARY
Standard C Library (libc, -lc)
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() function obtains the value of the spawn-
flags attribute from the attributes object referenced by attr.
The posix_spawnattr_setflags() function sets the spawn-flags attribute in
an initialized attributes object referenced by attr.
The spawn-flags attribute is used to indicate which process attributes
are to be changed in the new process image when invoking posix_spawn() or
posix_spawnp(). It is the bitwise-inclusive OR of zero or more of the
following flags (see posix_spawn()):
POSIX_SPAWN_RESETIDS
POSIX_SPAWN_SETPGROUP
POSIX_SPAWN_SETSIGDEF
POSIX_SPAWN_SETSIGMASK
POSIX_SPAWN_SETSCHEDPARAM
POSIX_SPAWN_SETSCHEDULER
These flags are defined in <spawn.h>. The default value of this
attribute is as if no flags were set.
RETURN VALUES
The posix_spawnattr_getflags() and posix_spawnattr_setflags() functions
return zero.
