posix_spawn_file_actions_destroy, posix_spawn_file_actions_init — destroy
and initialize spawn file actions object (ADVANCED REALTIME)
The posix_spawn_file_actions_destroy() function shall destroy the object
referenced by file_actions; the object becomes, in effect,
uninitialized. An implementation may cause
posix_spawn_file_actions_destroy() to set the object referenced by
file_actions to an invalid value. A destroyed spawn file actions object
can be reinitialized using posix_spawn_file_actions_init(); the results
of otherwise referencing the object after it has been destroyed are undefined.
The posix_spawn_file_actions_init() function shall
initialize the object referenced by file_actions to contain no file
actions for posix_spawn() or posix_spawnp() to perform.
A spawn file actions object is as defined in
The effect of initializing an already initialized spawn file
actions object is undefined.
Upon successful completion, these functions shall return zero; otherwise, an
error number shall be returned to indicate the error.
The posix_spawn_file_actions_init() function shall fail if:
- Insufficient memory exists to initialize the spawn file actions
The posix_spawn_file_actions_destroy() function may fail
- The value specified by file_actions is invalid.
The following sections are informative.
These functions are part of the Spawn option and need not be provided on all
