Detailed Description

These functions manage the Strophe event loop.

Simple tools can use xmpp_run() and xmpp_stop() to manage the life cycle of the program. A common idiom is to set up a few initial event handers, call xmpp_run(), and then respond and react to events as they come in. At some point, one of the handlers will call xmpp_stop() to quit the event loop which leads to the program terminating.

More complex programs will have their own event loops, and should ensure that xmpp_run_once() is called regularly from there. For example, a GUI program will already include an event loop to process UI events from users, and xmpp_run_once() would be called from an idle function.

Function Documentation

◆ xmpp_run_once()

void xmpp_run_once ( xmpp_ctx_t *  ctx,
const unsigned long  timeout 

Run the event loop once.

This function will run send any data that has been queued by xmpp_send and related functions and run through the Strophe even loop a single time, and will not wait more than timeout milliseconds for events. This is provided to support integration with event loops outside the library, and if used, should be called regularly to achieve low latency event handling.

◆ xmpp_run()

void xmpp_run ( xmpp_ctx_t *  ctx)

Start the event loop.

This function continuously calls xmpp_run_once and does not return until xmpp_stop has been called.

◆ xmpp_stop()

void xmpp_stop ( xmpp_ctx_t *  ctx)

Stop the event loop.

This will stop the event loop after the current iteration and cause xmpp_run to exit.
