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():
           _XOPEN_SOURCE >= 500
               || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L
               || /* Glibc up to and including 2.19: */ _BSD_SOURCE

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 filesystem, 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 directory specified in path 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.

       ENOTDIR
              fd does not refer to a directory.

CONFORMING TO

       POSIX.1-2001, POSIX.1-2008, SVr4, 4.4BSD.

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 working directory.  The current working
       directory is left unchanged by execve(2).
