Same as @ref AutoFunctionTrace, but traces to @c stdlog. |
||||||
|
|
||||||
|
If you link to the library @c libmrwautofunctiontracestdlog using |
||||||
|
a linker option such as: @c -lmrwautofunctiontracestdlog and you |
||||||
|
must enable the GNU Compiler Collection specific function trace |
||||||
|
feature with compile and link option @c -finstrument-functions |
||||||
|
then you get an automatical function trace, that traces to @c |
||||||
|
stdlog. You don't need to change a single line in your code! |
