ptree_unregister_handler(3PICLTREE)			  PICL Plug-In Library Functions		       ptree_unregister_handler(3PICLTREE)

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.
