textport Subroutine

GL3.2 for AIX: Graphics Library (GL) Technical Reference

textport Subroutine

Purpose

Allocates an area of the screen for the textport.

Libraries

Graphics Library

C (libgl.a)

FORTRAN (libfgl.a)

C Syntax

void textport
(Screencoord left, Screencoord right,
Screencoord bottom, Screencoord top)

FORTRAN Syntax

SUBROUTINE TEXTPO(left, right, bottom, top)
INTEGER*4 left, right, bottom, top

Note: For FORTRAN users, this subroutine accepts long integer parameters (INTEGER*4) when started from a FORTRAN program, although it accepts short integers when started from a C program. The C and FORTRAN syntax shown here reflect this difference.

Description

The textport subroutine allocates an area on the screen for the textport window.

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

Parameters

left	Specifies the x screen coordinate for the left side of the textport.
right	Specifies the x screen coordinate for the right side of the textport.
bottom	Specifies the y screen coordinate for the bottom of the textport.
top	Specifies the y screen coordinate for the top of the textport.

Example

The example C language program tpbig.c uses the textport subroutine to define a textport.

Implementation Specifics

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