Important note Important

This API cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported with /ZW.

char *_getdcwd_nolock( 
   int drive,
   char *buffer,
   int maxlen 
);
wchar_t *_wgetdcwd_nolock( 
   int drive,
   wchar_t *buffer,
   int maxlen 
);

drive

Disk drive.

buffer

Storage location for the path.

maxlen

Maximum length of path in characters: char for _getdcwd and wchar_t for _wgetdcwd.

_getdcwd_nolock and _wgetdcwd_nolock are identical to _getdcwd and _wgetdcwd, respectively, except that they are not protected from interference by other threads. They might be faster because they do not incur the overhead of locking out other threads. Use these functions only in thread-safe contexts such as single-threaded applications or where the calling scope already handles thread isolation.
