posix_spawnattr_destroy() -- 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);

The posix_spawnattr_destroy() function destroys the spawn attributes object pointed to by attr. You can reinitialize the destroyed object with the posix_spawnattr_int() function. A destroyed attr attributes object

The posix_spawnattr_init() function initializes the spawn attributes object pointed to by attr with the default value for all of the individual attributes.

A spawn attributes object is of type posix_spawnattr_t (defined in <spawn.h>). This object specifies the inheritance of process attributes across a spawn operation.

A spawn attributes object (after possible modification by setting individual attribute values) can modify the behavior of the posix_spawn() and posix_spawnp(). function. Once a spawn attribute object has been used to spawn a new process, any function affecting that attributes object (including destruction) has no effect whatsoever on the spawned process.

PARAMETERS

attr: Points to a spawn attributes object.

RETURN VALUES

On success, the posix_spawnattr_destroy() and posix_spawnattr_init() functions return 0.

Otherwise, these functions return one of the following error numbers:

ENOMEM: There is not enough memory to initialize the spawn attributes object.
EINVAL: The attr argument contains an invalid value.
