Obtaining the name of the caller function
-
Is there any way to obtain the name of the caller function in VC++? eg: Func1() { Func2() } I need to get the name of Func1() from Func2() using code. Any help would be appreciated. Thanks, John
Unfortunately, there's no way to do that directly. The compiler does create a
#definesymbol called__FUNCTION__, that is the name of the current function. You could modify your code as follows:void Func2(char *caller);
void Func1()
{
Func2(__FUNCTION__);
}
void Func2(char *caller)
{
TRACE(_T("Func2 called by %s.\r\n"),caller);
}Everywhere you call
Func2useFunc2(__FUNCTION__);.

Look at the DbgHelp API, in particular the symbol handling functions. There are articles here on CP about 'call-stack tracing' that will also help. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/dbghelp_functions.asp[^] ...cmk Save the whales - collect the whole set

Hello, The callstack[^] is a usefull place to look for a function address and name. The only problem is that this only works in debug builds. Do you need this also in release builds? If so, you have to provide the *.pdb file with your application, which reveals vital information about your application. Hope this helps.

This may be a VC7.1 feature, as that's the only compiler where I've used it. There's no option required to enable it. The value is the fully-resolved name of the function, e.g.
base1::base2::...::function.

__FUNCTION__and the other related macros aren't in VC 6 :( --Mike-- Visual C++ MVP :cool: LINKS~! Ericahist | PimpFish | CP SearchBar v3.0 | C++ Forum FAQ "That probably would've sounded more commanding if I wasn't wearing my yummy sushi pajamas." -- Buffy -

Setting aside the problems of getting the human-readable name of functions, walking the callstack at runtime is problematic.
