Delete a file.

int remove(
   const char *path
);
int _wremove(
   const wchar_t *path
);

path
Path of file to be removed.

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, specifies a directory, or the file is open, or to ENOENT to indicate that the filename or path was not found.

See _doserrno, errno, _sys_errlist, and _sys_nerr for more information on these and other return codes.

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.

By default, this function's global state is scoped to the application. To change this, see Global state in the CRT.

For additional compatibility information, see Compatibility.
