int _mkdir( const char *dirname );
or
int _wmkdir( const wchar_t *dirname );
Return Value:
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
Parameter
dirname - Path for new directory
Remarks:
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.
