POSIX_SPAWNATTR_INIT(3)	 BSD Library Functions Manual  POSIX_SPAWNATTR_INIT(3)

NAME
     posix_spawnattr_init, posix_spawnattr_destroy -- initialize and destroy
     spawn attributes object

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <spawn.h>

     int
     posix_spawnattr_init(posix_spawnattr_t * attr);

     int
     posix_spawnattr_destroy(posix_spawnattr_t * attr);

DESCRIPTION
     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	ob-
     ject.  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 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 af-
     fect any process that has been spawned in this way.

RETURN VALUES
     Upon successful completion, posix_spawnattr_init()	and
     posix_spawnattr_destroy() return zero; otherwise, an error	number is re-
     turned to indicate	the error.

ERRORS
     The posix_spawnattr_init()	function will fail if:

     [ENOMEM]		Insufficient memory exists to initialize the spawn at-
			tributes object.

SEE ALSO

STANDARDS
     The posix_spawnattr_init()	and posix_spawnattr_destroy() functions	con-
     form to IEEE Std 1003.1-2001 ("POSIX.1").

HISTORY
     The posix_spawnattr_init()	and posix_spawnattr_destroy() functions	first
     appeared in FreeBSD 8.0.
