POSIX_SPAWNATTR_GETFLAGS(3) FreeBSD Library Functions Manual POSIX_SPAWNATTR_GETFLAGS(3)

posix_spawnattr_getflags, posix_spawnattr_setflags
get and set the spawn-flags attribute of a spawn attributes object

Standard C Library (libc, -lc)

#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);

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()):

These flags are defined in <spawn.h>. The default value of this attribute is as if no flags were set.

The posix_spawnattr_getflags() and posix_spawnattr_setflags() functions return zero.

posix_spawn(3), posix_spawnattr_destroy(3), posix_spawnattr_init(3), posix_spawnp(3)

The posix_spawnattr_getflags() and posix_spawnattr_setflags() functions conform to IEEE Std 1003.1-2001 (“POSIX.1”).

The posix_spawnattr_getflags() and posix_spawnattr_setflags() functions first appeared in FreeBSD 8.0.
