Syntax:
#include <stdlib.h>Description:
The free() function deallocates the space pointed to by ptr, freeing it up for future use. ptr must have been used in a previous call to |malloc()|, |calloc()|, or |realloc()|.
Example:
typedef struct data_type {
int age;
char name[20];
} data;
data *willy;
willy = (data*) malloc( sizeof(willy) );
...
free( willy );
