Detailed Description

Class to manage trap signaling hardware watchpoins.

Member Function Documentation

add()

bool KittyPerfTrap::add	(	pid_t	tid,
		uintptr_t	addr,
		KT_WATCH_TYPE	bp_type,
		KT_WATCH_LEN	bp_len )

Adds a new trap signaling hardware watchpoint to the watch list.

Parameters

tid	The thread ID to attach the watchpoint to.
addr	The address to watch.
bp_type	The type of watchpoint (read, write, or read/write).
bp_len	The length of the watchpoint in bytes.

Returns

True if the watchpoint was added successfully, false otherwise.
