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