Function Documentation

◆ clear_waitpid_callback()

void clear_waitpid_callback ( waitpid_callback_t * ent )

Cancel a waitpid_callback_t, or clean up after one has triggered. Releases all storage held by ent.

Definition at line 98 of file waitpid.c.

◆ HT_HEAD()

static HT_HEAD	(	HT_PROTOTYPE(	process_map,
		HT_PROTOTYPE(	waitpid_callback_t
	)

static

Definition at line 58 of file waitpid.c.

◆ notify_pending_waitpid_callbacks()

void notify_pending_waitpid_callbacks ( void )

Use waitpid() to wait for all children that have exited, and invoke any callbacks registered for them.

Definition at line 141 of file waitpid.c.

◆ notify_waitpid_callback_by_pid()

static void notify_waitpid_callback_by_pid	(	pid_t	pid,
		int	status
	)

static

Helper: find the callback for pid; if there is one, run it, reporting the exit status as status.

Definition at line 119 of file waitpid.c.

◆ process_map_entries_eq_()

static unsigned int process_map_entries_eq_	(	const waitpid_callback_t *	a,
		const waitpid_callback_t *	b
	)

◆ process_map_entry_hash_()

static unsigned int process_map_entry_hash_ ( const waitpid_callback_t * ent )
