36<H2>Description</H2>
37<P>Clears an event flag member of the event structure.</P>
38<P><EM><B>event</B></EM> is a pointer to an event structure. <CODE>OS_ClearEvent()</CODE> will clear the event flag member of <B><I>event</I></B> for the bit indicated by <B><I>clearBit</I></B>.</P>
39<P><CODE>OS_ClearAllEvent()</CODE> will clear all bits. In other words, it sets the event flag of <B><I>event</I></B> to 0.</P>
40<P>Internally, this just sets a value for the member of the structure, so the system will not switch threads as a result of this function.</P>
