free function

free is used to return allocated memory to the system.

	Library:   sdlib.h

	Prototype: void free(void *s);

	Syntax:    char *StrPtr;
		   StrPtr = (char *) malloc(100);
                   free(StrPtr);

Notes:

• If you use malloc inside a loop and dont free the memory, you run the risk of the program crashing.

• If a program ends without issuing a free, any allocated memory is returned to the system.
