                    | Defined in header  <cstdlib> | ||
| void free( void* ptr ); | ||
Deallocates the space previously allocated by std::malloc(), std::calloc() or std::realloc(). If ptr is null-pointer, the function does nothing.
The behavior is undefined if ptr does not match a pointer returned earlier by std::malloc(), std::calloc() or std::realloc(). Also, the behavior is undefined if the memory area referred to by ptr has already been deallocated, that is, free() or std::realloc() has already been called with ptr as the argument and no calls to std::malloc(), std::calloc() or std::realloc() resulted in a pointer equal to ptr afterwards.
