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 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.

RETURN VALUES

     Upon successful completion, posix_spawnattr_init() and posix_spawnattr_destroy() return zero; otherwise, an error number is returned to indi-
     cate the error.

ERRORS

     The posix_spawnattr_init() function will fail if:

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

STANDARDS

     The posix_spawnattr_init() and posix_spawnattr_destroy() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

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