NAME

       chdir, chroot - change default directory

SYNOPSIS

       chdir(dirname)
       char *dirname;

       chroot(dirname)
       char *dirname;

DESCRIPTION

       Dirname	is the address of the pathname of a directory, terminated by a null byte.  Chdir causes this directory to become the current work-
       ing directory, the starting point for path names not beginning with `/'.

       Chroot sets the root directory, the starting point for path names beginning with `/'.  The call is restricted to the super-user.

SEE ALSO

       cd(1)

DIAGNOSTICS

       Zero is returned if the directory is changed; -1 is returned if the given name is not that of a directory or is not searchable.

ASSEMBLER

       (chdir = 12.)

NAME

       chdir - change current working directory

SYNOPSIS

       #include <unistd.h>

       int chdir(const char *path)

DESCRIPTION

       Path  is  the  pathname	of  a directory.  Chdir causes this directory to become the current working directory, the starting point for path
       names not beginning with ``/''.

       In order for a directory to become the current directory, a process must have execute (search) access to the directory.

RETURN VALUE

       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] The path name exceeds PATH_MAX characters.

       [ENOENT]       The named directory does not exist.

       [ELOOP]	      Too many symbolic links were encountered in translating the pathname.  (Minix-vmd)

       [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.
