pcmk__assert_alloc

#define pcmk__assert_alloc	(		nmemb,

Function Documentation

pcmk__add_mainloop_ipc()

int pcmk__add_mainloop_ipc	(	crm_ipc_t *	ipc,
		int	priority,
		void *	userdata,
		const struct ipc_client_callbacks *	callbacks,
		mainloop_io_t **	source )

Connect to IPC and add it as a main loop source.

Parameters

[in,out]	ipc	IPC connection to add
[in]	priority	Event source priority to use for connection
[in]	userdata	Data to register with callbacks
[in]	callbacks	Dispatch and destroy callbacks for connection
[out]	source	Newly allocated event source

Returns

Standard Pacemaker return code

Note

On failure, the caller is still responsible for ipc. On success, the caller should call mainloop_del_ipc_client() when source is no longer needed, which will lead to the disconnection of the IPC later in the main loop if it is connected. However the IPC disconnects, mainloop_gio_destroy() will free ipc and source after calling the destroy callback.
