PTREE_UNREGISTER_HANDLER(3PICLTREE) PICL Plug-In Library Functions

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.
