CHDIR(2)                   Linux Programmer's Manual                  CHDIR(2)



NAME
       chdir, fchdir - change working directory

SYNOPSIS
       #include <&lt;unistd.h>&gt;

       int chdir(const char *path);
       int fchdir(int fd);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       fchdir(): _BSD_SOURCE || _XOPEN_SOURCE >= 500

DESCRIPTION
       chdir() changes the current working directory of the calling process to
       the directory specified in path.

       fchdir() is identical to chdir();  the  only  difference  is  that  the
       directory is given as an open file descriptor.

RETURN VALUE
       On  success,  zero is returned.  On error, -1 is returned, and errno is
       set appropriately.

ERRORS
       Depending on the file system, other errors can be returned.   The  more
       general errors for chdir() are listed below:

       EACCES Search  permission  is denied for one of the components of path.
              (See also path_resolution(7).)

       EFAULT path points outside your accessible address space.

       EIO    An I/O error occurred.

       ELOOP  Too many symbolic links were encountered in resolving path.

       ENAMETOOLONG
              path is too long.

       ENOENT The file does not exist.

       ENOMEM Insufficient kernel memory was available.

       ENOTDIR
              A component of path is not a directory.

       The general errors for fchdir() are listed below:

       EACCES Search permission was denied on the directory open on fd.

       EBADF  fd is not a valid file descriptor.

CONFORMING TO
       SVr4, 4.4BSD, POSIX.1-2001.

NOTES
       The current working directory is the starting  point  for  interpreting
       relative pathnames (those not starting with '/').

       A child process created via fork(2) inherits its parent's current work-
       ing directory.  The current working  directory  is  left  unchanged  by
       execve(2).

       The prototype for fchdir() is only available if _BSD_SOURCE is defined,
       or _XOPEN_SOURCE is defined with the value 500.
