posix_spawnattr_init(3c)
Standard C Library Functions
posix_spawnattr_destroy(3C)
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_spaw‐
nattr_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 pro‐
vided.
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_spaw‐
nattr_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.
