remove, _wremove

Delete a file.

Syntax

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

Parameters

path
Path of file to be removed.

Return Value

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 wasn't found.

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

Remarks

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.
