pjsua_buddy_update_pres method

int pjsua_buddy_update_pres(int buddy_id)

Update the presence information for the buddy. Although the library periodically refreshes the presence subscription for all buddies, some application may want to refresh the buddy's presence subscription immediately, and in this case it can use this function to accomplish this.

Note that the buddy's presence subscription will only be initiated if presence monitoring is enabled for the buddy. See #pjsua_buddy_subscribe_pres() for more info. Also if presence subscription for the buddy is already active, this function will not do anything.

Once the presence subscription is activated successfully for the buddy, application will be notified about the buddy's presence status in the on_buddy_state() callback.

@param buddy_id Buddy identification.

@return PJ_SUCCESS on success, or the appropriate error code.
