NAME
       dgmstat - get file status

SYNOPSIS
       #include <sys/types.h>
       #include <sys/stat.h>

       int    dgmstat (path, bufferptr)
       char   * path;
       struct stat * bufferptr;

   where:
       path           Address of a pathname

       bufferptr     Address of a stat buffer to fill

DESCRIPTION
       Dgmstat returns the current attributes of the file pointed to by
       path into the status buffer at the location specified by bufferptr.
       If path refers to a symbolic link, file status for the target of the
       symbolic link is returned.  Furthermore, if path (after symbolic link
       resolution, if any) refers to a mount point for a file system, status
       information for the mounted on directory is returned.

       The subject file must be of type `ordinary-disk-file', `directory',
       `block-special-file', `character-special-file', or `fifo-special-
       file'.

       See stat(2) for more details about the information returned in the
       stat structure.

       If dgmstat fails, the contents of the buffer are undefined.

ACCESS CONTROL
       Read, write, or execute permission of the named file is not required,
       but the process must have permission to resolve path.

RETURN VALUE
       0      The dgmstat operation was successful.

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

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

       EFAULT         Bufferptr points to an invalid address.

       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.
