Defining macros with respect to the source file that calls it

[saswins]

Hi,


I am using a macro(debug_macro) for logging debug info that is defined in log.h file. I need to map this debug_macro to process specific debug macros. I have explained my expectations in the below example.


log.h
=======
#if callee==process1
#define debug_macro proc1_debug_macro
#if callee==process2
#define debug_macro proc2_debug_macro


process1.c
===========
#include log.h
debug_macro <<<<<====== this one should call proc1debug_macro


process2.c
===========
#include log.h
debug_macro <<<<==== this one should call proc2_debug_macro


I am newbie to C programming.Please provide me any suggessions on how to implement this ? Any help would be much appreciated.


Thanks,

Put a flag on the command line to select the definition?

I'm not really sure why you want a "per process" definition in a single header. Why not just define the same name for different applications?

What is the difference between proc1_debug_macro and proc2_debug_macro?

Why not put into your macro something to print the result of getpid(), or whatever other API you have to distinguish separate running instances of your code.

My preference would be to have a non-macro logging API - with an init function to set process specific stuff. Then use macro's to include __FILE__, __LINE__, and that sort of stuff when calling the log api.
