Deallocate Memory

Description
Example
void free(ptr}
void *ptr;
memory. c in rts. src
The free function deallocates memory space (pointed to by ptr) that was
previously allocated by a malloc, calloc, or realloc call. This makes the
memory space available again. If you attempt to free unallocated space, the
function takes no action and returns. For more information, see Section
5.1 .3, Dynamic Memory Allocation, on page 5-4.
This example allocates 10 bytes and then frees them.
char *x;
x = malloc(lO);
free (x) ;
/* allocate 10 bytes
/* free 10 bytes
*/
