/*
15
 * Purpose: Provides internal function tracing in the form of a stack.
16
 *      The FUNC_ENTER() macro adds the function name to the function
17
 *              stack whenever a function is entered.
18
 *      As the functions return with FUNC_LEAVE,
19
 *      entries are removed from the stack.
20
 *
21
 *      A function stack has a fixed maximum size.  If this size is
22
 *      exceeded then the stack will be truncated and only the
23
 *      first called functions will have entries on the stack. This is
24
 *      expected to be a rare condition.
