MPE_Draw_line - Draws a line on an X11 display

#include "mpe.h" 
int MPE_Draw_line( handle, x1, y_1, x2, y_2, color )
MPE_XGraph handle;
int        x1, y_1, x2, y_2;
MPE_Color  color;

handle
- MPE graphics handle
x1,y_1
- pixel position of one end of the line to draw. Coordinates are upper-left origin (standard X11)
x2,y_2
- pixel position of the other end of the line to draw. Coordinates are upper-left origin (standard X11)
color
- Color `index` value. See 'MPE_MakeColorArray'. By default, the colors

The Fortran interface to this routine is different from its C counterpart and it has an additional argument, ierr, at the end of the argument list, i.e. the returned function value (the error code) in C interface is returned as the additional argument in Fortran interface. The Fortran interface is invoked with the CALL statement.
All MPI and MPE objects, MPI_Comm, MPE_XGraph and MPE_Color, are of type INTEGER in Fortran.
