Hi!
I want to build a "function call logger" .dll which could write out each
function call with the call parameters to a logfile.
Original working of a "program.exe" and "funcs.dll":
-------------------- -------------------------
| program.exe | | funcs.dll |
| | | |
| imports: func_a <==================== exports: func_a |
| | | |
-------------------- -------------------------
If I want to log what functions the "program.exe" calls I have to make
an other "funcs.dll" as a replacement. The original "funcs.dll" can be
renamed as "funcs-orig.dll".
Now this should work as follows:
-------------------- -------------------- -------------------------
| program.exe | | funcs.dll | | funcs-orig.dll |
| | | | | |
| | | imports: func_a <===== exports: func_a |
| imports: func_a <====exports: func_a | | |
| | | | | |
-------------------- ---------|----------- -------------------------
|
\|/
logfile.txt
The problem is that in the new source code I have to use 2 func_a: the
first one to export to the program.exe and the second one to import from
funcs-orig.dll like this:
void func_a() { // this is the new exported function
// log to logfile.txt
func_a(); // this shoud be a call to funcs-orig.dll's func_a()
}
Is it possible to make something like this?
Thanks,
NMarci
