NAME
       plgdiori - Get plot orientation


SYNOPSIS
       plgdiori(p_rot)


DESCRIPTION
       Get  plot orientation parameter which is multiplied by 90 degrees to obtain the angle of rotation.  Note,
       arbitrary rotation parameters such as 0.2 (corresponding to 18  degrees)  are  possible,  but  the  usual
       values  for the rotation parameter are 0., 1., 2., and 3. corresponding to 0 degrees (landscape mode), 90
       degrees  (portrait  mode),  180  degrees  (seascape  mode),  and  270  degrees  (upside-down  mode).   If
       plsdiori(3plplot) has not been called the default value pointed to by p_rot will be 0.

       Redacted form: plgdiori(p_rot)

       This function is not used in any examples.


ARGUMENTS
       p_rot (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the orientation parameter.
