NAME
ptree_unregister_handler - unregister the event handler for the event SYNOPSIS
cc [flag ...] file ... -lpicltree [library ...] #include <picltree.h> void ptree_register_handler(const char *ename, void (*evt_handler)(const char *ename, const void *earg, size_t size, void *cookie), void *cookie); DESCRIPTION
The ptree_unregister_handler() function unregisters the event handler for the specified event. The argument ename specifies the name of the PICL event for which to unregister the handler. The argument evt_handler specifies the event handler function. The argument cookie is the pointer to the caller-specific data given at the time of registration of the handler. If the handler being unregistered is currently executing, then this function will block until its completion. Because of this, locks acquired by the handlers should not be held across the call to ptree_unregister_handler() or a deadlock may result. The ptree_unregister_handler() function must not be invoked from the handler that is being unregistered. RETURN VALUES
This function does not return a value. ATTRIBUTES

NAME
ptree_post_event - post a PICL event SYNOPSIS
cc [ flag... ] file... -lpicltree [ library... ] #include <picltree.h> int ptree_post_event(const char *ename, const void *earg, size_t size, void (*completion_handler)(char *ename, void *earg, size_t size)); DESCRIPTION
The ptree_post_event() function posts the specified event and its arguments to the PICL framework. The argument ename specifies a pointer to a string containing the name of the PICL event. The arguments earg and size specify a pointer to a buffer containing the event arguments and size of that buffer, respectively. The argument completion_handler specifies the completion handler to be called after the event has been dispatched to all handlers. A NULL value for a completion handler indicates that no handler should be called. The PICL framework invokes the completion handler of an event with the ename, earg, and size arguments specified at the time of the posting of the event. PICL events are dispatched in the order in which they were posted. They are dispatched by executing the handlers registered for that event. The handlers are invoked in the order in which they were registered. New events will not begin execution until all previous events have finished execution. Specifically, an event posted from an event handler will not begin execution until the current event has finished execution. The caller may not reuse or reclaim the resources associated with the event name and arguments until the invocation of the completion han- dler. The completion handlers are normally used to reclaim any resources allocated for the posting of an event. RETURN VALUES
Upon successful completion, 0 is returned. On failure, a non-negative integer is returned to indicate an error, the event is not posted, and the completion handler is not invoked. ERRORS
PICL_INVALIDARG Invalid argument PICL_FAILURE General system failure ATTRIBUTES
