Get calling function in a function?

[Joerg Battermann]

Hello there,

I have a quick question:

When calling a function B from within a function A, is it possible get
information about the calling function A (e.g. name, values passed over
etc) from within the function B?

The reason why I am asking, is, for example when handling exceptions or
logging errors so I know what exactly happened.


Thanks and all the best,

"Name"? - Yes.
"Values" passed over - No.

Like me, you've discovered that "Good" code doesn't just break, it get's
broken by "Bad" data - and that's conspicuously /missing/ from .Net's
built-in StackTrace.

I'd suggest building your own module to augment the built in StackTrace,
marking the entry and exit points of each [major] method (/with/
arguments and return values), but it would have to be a Global thing
within each application - you don't want to be passing it around into
practically every function - don't know if that would be an issue for you.

HTH,

Phil,

thanks for the reply. I'll give the later one a try (because the value
often is the critical part in my case). For others who need reference,
here's some information concerning .net's stacktrace:
