posix_spawnattr_init, posix_spawnattr_destroy — initialize and destroy
spawn attributes object
Standard C Library (libc, -lc)
posix_spawnattr_init(posix_spawnattr_t * attr);
posix_spawnattr_destroy(posix_spawnattr_t * attr);
The 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
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 indi‐
vidual 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 func‐
tion affecting the attributes object (including destruction) will not
affect any process that has been spawned in this way.
Upon successful completion, posix_spawnattr_init() and
posix_spawnattr_destroy() return zero; otherwise, an error number is
returned to indicate the error.
The posix_spawnattr_init() function will fail if:
[ENOMEM] Insufficient memory exists to initialize the spawn
file actions object.

The posix_spawnattr_init() and posix_spawnattr_destroy() functions con‐
form to IEEE Std 1003.1-2001 (“POSIX.1”).
The posix_spawnattr_init() and posix_spawnattr_destroy() functions first
appeared in FreeBSD 8.0.
