chdir(2)                   DG/UX 4.30                    chdir(2)



     NAME
          chdir - Change the working directory of the calling process.

     SYNOPSIS
          int   chdir  (path)
          char *          path;

     PARAMETERS
          path           Address of a pathname.

     DESCRIPTION
          <Path> points to a pathname naming a directory that is made
          the current working directory of the calling process.  If
          <path> refers to a symbolic link, the target of the symbolic
          link is made the current working directory.  The current
          working directory is the starting point of subsequent
          searches for pathnames that do not begin with '/'.

          If the call fails, the current working directory is not
          changed.

     ACCESS CONTROL
          The calling process must have execute permission to the
          named directory.

          The process must have permission to resolve <path>.

     RETURN VALUE
          0              The current directory was successfully
                         changed.


          -1             An error occurred. Errno is set to indicate
                         the error.

     EXCEPTIONS
          Errno may be set to one of the following error codes:


          EACCES         Execute permission to the directory is
                         denied.


          ENOTDIR        The named file is not a directory.


          ENOENT         The file the pathname resolved to does not
                         exist.


          ENOENT         A non-terminal component of the pathname does
                         not exist.

          ENOTDIR        A non-terminal component of the pathname was
                         not a directory or symbolic link.


          ENAMETOOLONG   The pathname exceeds the length limit for
                         pathnames.


          ENAMETOOLONG   A component of the pathname exceeds the
                         length limit for filenames.


          ENOMEM         There are not enough system resources to
                         resolve the pathname or to expand a symbolic
                         link.


          ELOOP          The number of symbolic links encountered
                         during pathname resolution exceeded
                         MAXSYMLINKS.  A symbolic link cycle is
                         suspected.


          EPERM          The pathname contains a character not in the
                         allowed character set.


          EFAULT         The pathname does not completely reside in
                         the process's address space or the pathname
                         does not terminate in the process's address
                         space.
