My Project is having 15000 files and around 2000000 lines of code, Developers used fprintf (sdterr,”%s”,string) function to generate logs, Now we are asked to put time stamp on each log it is generated. Changing each file is not possible; we are planning to create our own “fprintf” function in one of our library. I’ll appreciate your guidance to solve this issue ( else some out of box ideas ).

Thanks in advance.
