The Microsoft C version 5.10 _setlogorg graphics function is used to
move the logical origin (0, 0) to the physical point (x, y). All other
points move the same direction and distance. This function is not
present in the C 6.00 graphics run-time library because it has been
replaced by the _setvieworg function.

The _setlogorg function is defined in the C 6.00 version of the
graph.h include file. Because of this, code that was originally
compiled under C 5.10 need not be changed before recompiling it under
C 6.00.

If a C 5.10 .OBJ containing a call to _setlogorg() needs to be linked
with C 6.00 .OBJ files and libraries, you will get an unresolved
external link error on _setlogorg. To work around this problem,
compile the following code under C 6.00 and link it in with the other
.OBJ files:

#include <graph.h>

#undef _setlogorg

struct xycoord _far _setlogorg(short x, short y)
{
     return(_setvieworg(x, y));
}
