S- function does not allow to specify the path name of the c file which it is supposed to identify during simulation. Where am I supposed to place the c program for the s function to identify.

Hmm... if you are writing an S-function by hand, then you should be able to add your other source files when you build it
>> mex file1.c file2.c
Lots more info here:

If you are new to S-functions and you just want to call your C function from a Simulink block, might I suggest you check out the Legacy Code Tool:

Hope this helps!
