remove, _wremove
Delete a file.
int remove(
const char *path
);
int _wremove(
const wchar_t *path
);
Параметры
- path
Path of file to be removed.
Возвращаемое значение
Each of these functions returns 0 if the file is successfully deleted. Otherwise, it returns -1 and sets errno either to EACCES to indicate that the path specifies a read-only file or the file is open, or to ENOENT to indicate that the filename or path was not found or that the path specifies a directory.
See _doserrno, errno, _sys_errlist, and _sys_nerr for more information on these and other return codes.
Заметки
The remove function deletes the file specified by path. _wremove is a wide-character version of _remove; the path argument to _wremove is a wide-character string. _wremove and _remove behave identically otherwise. All handles to a file must be closed before it can be deleted.
