Initialize a spawn file actions object
#include <spawn.h> int posix_spawn_file_actions_init( posix_spawn_file_actions_t *fact_p);
- A pointer to the spawn file action object that you want to initialize.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawn_file_actions_init() function initializes the object referenced by fact_p to contain no file actions for posix_spawn() or posix_spawnp() to perform. For information about destroying a spawn file actions object, see posix_spawn_file_actions_destroy() .
A spawn file actions object is an opaque data type that specifies a series of close(), dup2(), and open() actions to be performed by a posix_spawn() or posix_spawnp() operation in order to arrive at the set of open file descriptors for the child process, given the parent's set of open file descriptors. For more information, see posix_spawn() ).
Don't reinitialize a posix_spawn_file_actions_t object without destroying it. Repeated calls to posix_spawn_file_actions_init() with the same posix_spawn_file_actions_t object could result in a memory leak. In the BlackBerry 10 OS implementation, all get and set operations, as well as posix_spawn(), return EINVAL when attempting to reference a destroyed file actions object.
- An argument was invalid.
- Insufficient memory exists to initialize the spawn file actions object.
