File and Path Function

int chdir(const char *dirname);

int _chdir(const char *dirname);

int _wchdir(const wchar_t *dirname);

int _tchdir(const TCHAR *dirname);

Internationalization (I18n) Function Overview

The chdir and _chdir functions are used to set the process' working directory to dirname. If successful, 0 is returned; otherwise, -1 is returned and the global errno variable is set to ENOENT to indicate that the specified path could not be found.

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

_tchdir is the Windows-only Generic version of the function; with the _MBCS or _UNICODE compiler flags determining its mapping to either _chdir or _wchdir.

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 chdir.

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

Recommended Replacements*

ANSI UTF-8	chdir
ANSI UTF-16	convert and call chdir
Microsoft Windows MBCS	_chdir
Microsoft Windows Unicode	_wchdir
Microsoft Windows Generic	_tchdir
