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       ENOLINK		       The path argument points to a remote machine and the link to that machine is no longer active.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       ENOLINK		       The fildes argument points to a remote machine and the link to that machine is no longer active.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