Hi I have two files say : - forking.h & forking.c ...... forking.h contains the declaration of a function XYZ() & forking.c contains the definition of XYZ(). I want to call thix function XYZ() in gcc.c file. I tried looking into the makefile (that is created after configure) but could not find the file gcc.c. How should I go about using this XYZ() function in gcc.c ?? Regards Ankit
