Sets hardware breakpoint and activates it. 80x86 compatible processors support 4 hardware breakpoints. If all available slots are in use, function asks user to delete one of active breakpoints. Returns 0 on success and -1 on error or if user cancelled action. It is allowed to call Sethardwarebreakpoint "on the fly", i.e. when debugged application is running.
Note that hardware breakpoints are not supported by Windows 95 and Windows 98. To assure that you can use this function, call Plugingetvalue(VAL_HARDBP).

Parameters:
addr - address of breakpoint;
