posix_spawnattr_init, posix_spawnattr_destroy -- initialize and destroy spawn attributes
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 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.
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 conform to IEEE Std
The posix_spawnattr_init() and posix_spawnattr_destroy() functions first appeared in
FreeBSD 8.0 and imported for NetBSD 6.
