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
     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 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.

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

ERRORS
     The posix_spawnattr_init() function will fail if:

     [ENOMEM]		Insufficient memory exists to initialize the spawn
			file actions object.

SEE ALSO
     posix_spawn(3), posix_spawnp(3)

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.
