Are you certain that it is a memory leak, and not a memory
fragmentation problem?

Rational Purify checked the code, and reported memory leak on foo1
when we allocate memory. I assum e that the compiler will allocate a
new block of memory when foo1 returns. Then the memory allocated
within foo1 will remain in the system heap forever. However I have no
way to verify it.


The allocated memory will be returned to the system heap when the
program exits, if there is a memory leak. I don't see a memory leak
either. The function foo1 calls calloc and returns the resulting
pointer, then the pointer is freed in you code.

A couple of points to make though:

1. Main is not declared correctly. It should be one of the two
following examples:

int main(void)

---or---

int main(int argc, char **argv)

In either case, you need to have a return at the end of your main function.

2. Your cast in calloc is not necessary...unless you are using C++, but
then you would need to head on over to c.l.c++ to ask your question.
