Answer Posted / dwight schrute
suppose u have 2 files:
file1 has following functions:
A1
B1
C1
file12 has following functions:
A2
B2
C2
scenario:
A1 needs to use A2 in turn A2 needs to use B1.
A1 invokes A2;
A2 invokes B1;
for B1 to be available in file2 either shld be extern or in
header file which in turn exposes it to entire file2.
In order to minimize this exposure "pass B1 as a functional
pointer to A2".
