watch_add()

Create new watch_t and add it on the beginning of watches list.

Parametry

plugin	- plugin
fd	- fd to watch data for.
type	- type of watch.
handler	- handler of watch.
data	- data which be passed to handler.

Zwraca

Created watch_t. if type is either WATCH_READ_LINE or WATCH_WRITE_LINE than also allocate memory for buffer

EXPORTNOT void watch_handle

(

w)

watch_handle()

Handler for watches with type: WATCH_READ or WATCH_WRITE
Mark watch with w->removed = -1, to indicate that watch is in use. And it shouldn't be executed again. [If watch can or even must be executed twice from ekg_loop() than you must change w->removed by yourself.]

If handler of watch return -1 or watch was removed inside function [by watch_remove() or watch_free()]. Than it'll be removed.
ELSE Update w->started field to current time.

Parametry

w	- watch_t to handler

Do zrobienia:

We only check for w->removed == -1, maybe instead change it to: w->removed != 0
