Destroy a spawn file actions object
#include <posix_spawn_file_actions.h> int posix_spawn_file_actions_destroy( posix_spawn_file_actions_t *fact_p);
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawn_file_actions_destroy() function destroys the object referenced by fact_p; in effect, the object becomes uninitialized. An implementation may cause the destroyed spawn file actions object to be reinitialized using posix_spawn_file_actions_init(); the results of otherwise referencing the object after its been destroyed are undefined.
The posix_spawn_file_actions_init() function initializes the object referenced by fact_p such that it contains no file actions for posix_spawn() or posix_spawnp() to perform. A spawn file actions object is as defined in posix_spawn_file_actions_addclose(). The effect of initializing an already initialized spawn file actions object is undefined.
The posix_spawn_file_actions_destroy() function will render the posix_spawn_file_actions_t unusable. Before reusing the object, it must be initialized with posix_spawn_file_actions_init(), which includes calling posix_spawn_file_actions_destroy() on an already destroyed object. POSIX specifies that results are undefined when using a posix_spawnattr_t object after it has been destroyed. The QNX implementation will cause all get() and set() operations, as well as posix_spawn(), to return EINVAL when attempting to reference a destroyed attributes object.
Upon successful completion, posix_spawnattr_destroy() returns zero; otherwise, an error number is returned to indicate the error (errno).
