* Testing TRACE_Address ( ) API
|
|
* Finds tstfunc1,tstfunc2,tstfunc3 by name and makes sure their addresses match a trace address
|
|
*
|
|
* Test app prints addresses of function pointers, of these 3 functions. Comparison is done in make rule.
|
|
*
|
|
* This test tests TRACE_Address only for traces at the beginning of a function.
|
|
* It does not check traces that begin in the middle of a function.
