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

NAME
       chdir, fchdir - change working directory
SYNOPSIS
       #include <unistd.h>
       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 ||
           _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED
           || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L
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).
