NAME
chdir, fchdir - change working directory SYNOPSIS
#include <unistd.h> int chdir(const char *path); int fchdir(int fildes); DESCRIPTION
The chdir() and fchdir() functions cause a directory pointed to by path or fildes to become the current working directory. The starting point for path searches for path names not beginning with / (slash). The path argument points to the path name of a directory. The fildes argument is an open file descriptor of a directory. For a directory to become the current directory, a process must have execute (search) access to the directory. RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned, the current working directory is unchanged, and errno is set to indi- cate the error. ERRORS
The chdir() function will fail if: EACCES Search permission is denied for any component of the path name. EFAULT The path argument points to an illegal address. EINTR A signal was caught during the execution of the chdir() function. EIO An I/O error occurred while reading from or writing to the file system. ELOOP Too many symbolic links were encountered in translating path. ENAMETOOLONG The length of the path argument exceeds PATH_MAX, or the length of a path component exceeds NAME_MAX while _POSIX_NO_TRUNC is in effect. ENOENT Either a component of the path prefix or the directory named by path does not exist or is a null pathname. ENOLINK The path argument points to a remote machine and the link to that machine is no longer active. ENOTDIR A component of the path name is not a directory. The fchdir() function will fail if: EACCES Search permission is denied for fildes. EBADF The fildes argument is not an open file descriptor. EINTR A signal was caught during the execution of the fchdir() function. EIO An I/O error occurred while reading from or writing to the file system. ENOLINK The fildes argument points to a remote machine and the link to that machine is no longer active. ENOTDIR The open file descriptor fildes does not refer to a directory. ATTRIBUTES

NAME
chdir, fchdir -- change current working directory SYNOPSIS
#include <unistd.h> int chdir(const char *path); int fchdir(int fildes); DESCRIPTION
The path argument points to the pathname of a directory. The chdir() function causes the named directory to become the current working directory, that is, the starting point for path searches of pathnames not beginning with a slash, '/'. The fchdir() function causes the directory referenced by fildes to become the current working directory, the starting point for path searches of pathnames not beginning with a slash, '/'. In order for a directory to become the current directory, a process must have execute (search) access to the directory. RETURN VALUES
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error. ERRORS
The chdir() system call will fail and the current working directory will be unchanged if one or more of the following are true: [EACCES] Search permission is denied for any component of the path name. [EFAULT] Path points outside the process's allocated address space. [EIO] An I/O error occurred while reading from or writing to the file system. [ELOOP] Too many symbolic links were encountered in translating the pathname. This is taken to be indicative of a looping sym- bolic link. [ENAMETOOLONG] A component of a pathname exceeded {NAME_MAX} characters, or an entire path name exceeded {PATH_MAX} characters. [ENOENT] The named directory does not exist. [ENOTDIR] A component of the path prefix is not a directory. fchdir() will fail and the current working directory will be unchanged if one or more of the following are true: [EACCES] Search permission is denied for the directory referenced by the file descriptor. [EBADF] The argument fildes is not a valid file descriptor. [EINTR] fchdir() was interrupted by a signal. [EIO] An I/O error occurred while reading from or writing to the file system. [ENOTDIR] The file descriptor does not reference a directory. SEE ALSO
chroot(2) STANDARDS
The chdir() is expected to conform to IEEE Std 1003.1-1988 (``POSIX.1''). HISTORY
The fchdir() function call appeared in 4.2BSD. 4th Berkeley Distribution December 11, 1993 4th Berkeley Distribution
