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 errnois 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
pathpoints outside your accessible address space.
EIO
An I/O error occurred.
ELOOP
Too many symbolic links were encountered in resolving path.
ENAMETOOLONG
pathis too long.
ENOENT
The directory specified in pathdoes not exist.
ENOMEM
Insufficient kernel memory was available.
ENOTDIR
A component of pathis not a directory.

The general errors for fchdir() are listed below:

EACCES
Search permission was denied on the directory open on fd.
EBADF
fdis 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 aq/aq).

A child process created via fork(2) inherits its parent's current working directory. The current working directory is left unchanged by execve(2).
