Detailed Description

Guarded interface to Bell objects used by user applications.

Implements the system call interface for class Bell. All methods provided by this class are wrappers for the respective method from the base class, which provide additional synchronization by using the class Guarded.

Member Function Documentation

sleep()

static void GuardedBell::sleep ( unsigned int  ms )

inlinestatic

Creates a temporary bell object and sleep for the given timespan.

Parameters

ms	time in milliseconds
