Hi,

Could someone tell or show me how to free dynamically allocated 
memory in one function from another function or main ?

eg:
main()
{
 foo();
 }
 
char* foo()
{
 char *s = malloc(80);
 }

If this function is to return s, freeing it before return would not 
be a good idea, is that true ?
If it is, how would i then get access to s to free it ? It's out of 
scope, as silly as is i've tried free(s) from main, compiler says 
"what s?" of course.
Btw, i have thought about freeing it before returning, and it *seems* to 
work fine in DOS, but i don't know how safe that is. 
I also believe that in a multitask environment, that would be fatal if 
another program got a slice between free() and return, am i thinking 
straight here or not ?                     

Thanks,
