posix_spawnattr_init
() function initializes a spawn
attributes object attr with the default value for all of
the individual attributes used by the implementation. Initializing an already
initialized spawn attributes object may cause memory to be leaked.
The posix_spawnattr_destroy
() function
destroys a spawn attributes object. A destroyed attr
attributes object can be reinitialized using
posix_spawnattr_init
(). The object should not be
used after it has been destroyed.
A spawn attributes object is of type
posix_spawnattr_t (defined in
<spawn.h>
) and is used to
specify the inheritance of process attributes across a spawn operation.
The resulting spawn attributes object (possibly modified by
setting individual attribute values), is used to modify the behavior of
posix_spawn
() or
posix_spawnp
(). After a spawn attributes object has
been used to spawn a process by a call to a
posix_spawn
() or
posix_spawnp
(), any function affecting the
attributes object (including destruction) will not affect any process that
has been spawned in this way.
posix_spawnattr_init
() and
posix_spawnattr_destroy
() return zero; otherwise, an
error number is returned to indicate the error.
posix_spawnattr_init
() function will fail if:
ENOMEM
]posix_spawnattr_init
() and
posix_spawnattr_destroy
() functions conform to
IEEE Std 1003.1-2001 (“POSIX.1”).
posix_spawnattr_init
() and
posix_spawnattr_destroy
() functions first appeared in
FreeBSD 8.0 and imported for NetBSD
6.0.
