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():
       _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.

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).
