NAME

       AREDAM - Adds edge segments to an area map.

SYNOPSIS

       CALL AREDAM (MAP,XCA,YCA,LCA,IGI,IDL,IDR)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_aredam (int *map, float *xca, float *yca, int lca, int igi, int idl, int idr)

DESCRIPTION

       MAP         (an input/output array of type INTEGER) - An array containing an area map that
                   has been initialized by a call to ARINAM.

                   Note: As part of initializing the area map, ARINAM stores the dimension of MAP
                   in MAP(1); therefore, the dimension does not have to be given as an argument
                   in calls to AREDAM.)

       XCA         (an input array, dimensioned LCA, of type REAL) - The X coordinates, in the
                   user coordinate system, of the points defining an edge.

       YCA         (an input array, dimensioned LCA, of type REAL) - The Y coordinates, in the
                   user coordinate system, of the points defining an edge.

       LCA         (an input expression of type INTEGER) - The number of coordinates in XCA and
                   YCA.

       IGI         (an input expression of type INTEGER) - Identifier of the group to which the
                   edge belongs.

       IDL         (an input expression of type INTEGER) - Identifier of the area that lies to
                   the left of the edge.

       IDR         (an input expression of type INTEGER) - Identifier of the area that lies to
                   the right of the edge.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       The area-map array MAP must have been initialized by a call to ARINAM.  Each subsequent
       call to AREDAM adds to the area map the LCA-1 edge segments defined by the points whose
       user coordinates are in the arrays XCA and YCA.  (Points 1 and 2 define the first edge
       segment, points 2 and 3 define the next edge segment, points 3 and 4 the next one, and so
       on.)

EXAMPLES

       Use the ncargex command to see the following relevant examples: cardb1, cardb2, carfill,
       carline, carmap, arex01, cbex01, tareas, fsppoint.

ACCESS

       To use AREDAM or c_aredam, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.

MESSAGES

       See the areas man page for a description of all Areas error messages and/or informational
       messages.
