Использование в приложениях (Application usage)
If the application calling fscanf() has any objects of type
wint_t or wchar_t, it must also include the <wchar.h> header to
have these objects defined.
For functions that allocate memory as if by malloc(), the
application should release such memory when it is no longer
required by a call to free(). For fscanf(), this is memory
allocated via use of the 'm' assignment-allocation character.
