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       ENOLINK	       The path argument points to a remote machine and the link to that machine is no longer active.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       ENOLINK	  The fildes argument points to a remote machine and the link to that machine is no longer active.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

NAME

     chdir, fchdir -- change current working directory

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <unistd.h>

     int
     chdir(const char *path);

     int
     fchdir(int fd);

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 fd 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

     chdir() will fail and the current working directory will be unchanged if one or more of the following are true:

     [ENOTDIR]		A component of the path prefix is not a directory.

     [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.

     [ELOOP]		Too many symbolic links were encountered in translating the pathname.

     [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.

     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.

     [ENOTDIR]		The file descriptor does not reference a directory.

     [EBADF]		The argument fd is not a valid file descriptor.

     [EPERM]		The argument fd references a directory which is not at or below the current process's root directory.
