chdir (2)
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
DESCRIPTION
chdir() changes the current working directory pf 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 file system, 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 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 work-
ing directory. The current working directory is left unchanged by
execve(2).
The prototype for fchdir() is only available if _BSD_SOURCE is defined,
or _XOPEN_SOURCE is defined with the value 500.
