File and Path Function

int mkdir(const char *dirname);

int _mkdir(const char *dirname);

int _wmkdir(const wchar_t *dirname);

int _tmkdir(const TCHAR *dirname);

Internationalization (I18n) Function Overview

The mkdir and _mkdir functions create a new subdirectory. The functions return 0 if successful; else they return -1 and set the global variable errno with the error number.

On Windows platforms, _wmkdir is the wide-character version of _mkdir; its argument is a wide-character string. There is no ANSI wide-character equivalent.

_tmkdir is the Windows-only Generic version of the function; with the _MBCS or _UNICODE compiler flags determining its mapping to either _mkdir or _wmkdir.

I18n Issues

Use the appropriate version of the function as required for internationalization support.

On ANSI UTF-16 platforms, use a conversion function to convert the wide-character string to a multibyte-character string and then call mkdir.

See Pathnames for a discussion of path and filename considerations in an internationalized application.

Recommended Replacements*

ANSI UTF-8	mkdir
ANSI UTF-16	convert and call mkdir
Microsoft Windows MBCS	_mkdir
Microsoft Windows Unicode	_wmkdir
Microsoft Windows Generic	_tmkdir
