 MPE_XGraph handle;
 int        x1, y_1, x2, y_2;
 MPE_Color  color;
 

INPUT PARAMETERS

handle

- MPE graphics handle

x1,y_1

- pixel position of one end of the line to draw. Coordinates are upper-left origin (standard X11)

NOTES FOR FORTRAN INTERFACE

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.
