Not possible, in C you can use only call-by-value.
Except, of course, that you can pass pointers by value, which is exactly equivalent to call-by-reference.
There are many possible situations, but one of the most common is when passing a struct. It is not only more convenient and more efficient to pass a pointer to the structure than to pass a copy of it, it also allows functions to modify the structure and/or attach the structure to other data structures.
This is particularly true when doing pseudo-object-oriented programming in C; pointers to structures (equivalent to objects) are passed to many different functions (equivalent to methods) which may need to modify the members of the structures.
This is just the substitution of call-by-reference, not the thing itself. If you know Pascal or C++, you know what the real c-b-r is.
