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).
