realloc
free
 
Defined in header <cstdlib>
void free( void* ptr );
Desasigna el espacio previamente asignado por malloc(), calloc() o realloc(). Si ptr es nulo puntero, la función no hace nada .
Original:
Deallocates the space previously allocated by malloc(), calloc() or realloc(). If ptr is null-pointer, the function does nothing.

El comportamiento no está definido si ptr no coincide con un puntero devuelto anteriormente por malloc(), calloc() o realloc(). Además, el comportamiento es indefinido si el área de memoria se refiere a por ptr ya ha sido desasignado, es decir, free() o realloc() ya se ha llamado con ptr como el argumento y hay llamadas a malloc(), calloc() o realloc() resultó en un puntero igual a ptr después .
Original:
The behavior is undefined if ptr does not match a pointer returned earlier by malloc(), calloc() or realloc(). Also, the behavior is undefined if the memory area referred to by ptr has already been deallocated, that is, free() or realloc() has already been called with ptr as the argument and no calls to malloc(), calloc() or realloc() resulted in a pointer equal to ptr afterwards.
