* Name: posix_spawn_file_actions_addopen
|
|
*
|
|
* Description:
|
|
* The posix_spawn_file_actions_addopen() function adds an open operation
|
|
* to the list of operations associated with the object referenced by
|
|
* file_actions, for subsequent use in a call to posix_spawn() or
|
|
* posix_spawnp(). The descriptor referred to by fd is opened using
|
|
* the path, oflag, and mode arguments as if open() had been called on it
|
|
* prior to the new child process starting execution. The string path is
|
|
* copied by the posix_spawn_file_actions_addopen() function during this
|
|
* process, so storage need not be persistent in the caller.
|
|
*
|
|
* Input Parameters:
|
|
* file_actions - The posix_spawn_file_actions_t to append the action.
|
|
* fd - The file descriptor to be opened.
|
|
* path - The path to be opened.
|
|
* oflags - Open flags
|
|
* mode - File creation mode
|
|
*
|
|
* Returned Value:
|
|
* On success, these functions return 0; on failure they return an error
|
|
* number from <errno.h>.
