_mkdir, _wmkdir

Creates a new directory.

int _mkdir(
   const char *dirname 
);
int _wmkdir(
   const wchar_t *dirname 
);

Параметры

• dirname
  Path for a new directory.

Возвращаемое значение

Each of these functions returns the value 0 if the new directory was created. On an error, the function returns –1 and sets errno as follows.

• EEXIST
  Directory was not created because dirname is the name of an existing file, directory, or device.

• ENOENT
  Path was not found.

For more information about these and other return codes, see _doserrno, errno, _sys_errlist, and _sys_nerr.

Заметки

The _mkdir function creates a new directory with the specified dirname. _mkdir can create only one new directory per call, so only the last component of dirname can name a new directory. _mkdir does not translate path delimiters. In Windows NT, both the backslash ( \) and the forward slash (/ ) are valid path delimiters in character strings in run-time routines.

_wmkdir is a wide-character version of _mkdir; the dirname argument to _wmkdir is a wide-character string. _wmkdir and _mkdir behave identically otherwise.
