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 indicate 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ENOLINK The path argument points to a remote machine and the link to that machine is no longer active.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ENOLINK The fildes argument points to a remote machine and the link to that machine is no longer active.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.
