Create a trace for your function that automatically pops itself of
|
||||||
|
the fstack when it goes out of scope. Usage:
|
||||||
|
|
||||||
|
auto scope _t = new MTrace("funcName");
|
||||||
|
|
||||||
|
This is one of the few places where C++ is actually easier to use...
|
||||||
|
|
||||||
|
An alternative way to do the same thing:
|
||||||
|
|
||||||
|
dbg.trace("funcName");
|
||||||
|
scope(exit) dbg.untrace();
