NAME
posix_spawnattr_destroy, posix_spawnattr_init - destroy and initialize spawn attributes object SYNOPSIS
#include <spawn.h> int posix_spawnattr_destroy(posix_spawnattr_t *attr); int posix_spawnattr_init(posix_spawnattr_t *attr); DESCRIPTION
The posix_spawnattr_destroy() function destroys a spawn attributes object. A destroyed attr attributes object can be reinitialized using posix_spawnattr_init(). The results of otherwise referencing the object after it has been destroyed are undefined. An implementation can cause posix_spawnattr_destroy() to set the object referenced by attr to an invalid value. 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. Results are undefined if posix_spawnattr_init() is called specifying an already initialized attr attributes object. 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. No attributes other than those defined by IEEE Std 1003.1-200x are provided. The resulting spawn attributes object (possibly modified by setting individual attribute values), is used to modify the behavior of posix_spawn(3C) or posix_spawnp(3C). After a spawn attributes object has been used to spawn a process by a call to 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_destroy() and posix_spawnattr_init() return 0. 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. The posix_spawnattr_destroy() function may fail if: EINVAL The value specified by attr is invalid. ATTRIBUTES

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. SEE ALSO
posix_spawn(3), posix_spawnp(3) 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. AUTHORS
