getorigin Subroutine

Purpose

Returns the position of a window.

Libraries

Graphics Library

C (libgl.a)

FORTRAN (libfgl.a)

C Syntax

void getorigin(Int32 *x, Int32 *y)

FORTRAN Syntax

SUBROUTINE GETORI(x, y)
INTEGER*4 x, y

Description

The getorigin subroutine returns the position (in pixels) of the lower-left corner of the current window. A window must be open for this subroutine to work.

Call the winopen subroutine to open a window, or the winset subroutine to choose the current window.

Note: This subroutine cannot be used to add to a display list.

Parameters

x	Specifies a pointer to the location in which to return the x position (in pixels) of the lower left corner of the window.
y	Specifies a pointer to the location in which to return the y position (in pixels) of the lower left corner of the window.

Example

The example C language program paint.c uses the getorigin subroutine to determine the origin of the window.

Implementation Specifics

This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
