Defines functions of Computer Graphics Interface related to obtaining graphical and non-graphical input from a Virtual Device of device class INPUT or OUTIN. Also defines functions to support echoing of input operations on separate Virutal Devices. Should be read in conjunction with ISO/IEC 9636-1, ISO/IEC 9636-2 and ISO/IEC 9636-4. The relationship of this part to the other parts of ISO/IEC 9636 is described in ISO/IEC 9636-1 and in clause 4.

This part of ISO/IEC 9636 defines those functions of the Computer Graphics Interface concerned with obtaining graphical and non-graphical input from a Virtual Device of device class INPUT or OUTIN. This part of ISO/IEC 9636 also defines functions to support echoing of input operations on separate Virtual Devices.

This part of ISO/IEC 9636 is part 5 of ISO/IEC 9636, and should be read in conjunction with ISO/IEC 9636-1, ISO/IEC 96362, and ISO/IEC 9636-4. The relationship of this part of ISO/IEC 9636 to the other parts of of ISO/IEC 9636 is described in ISO/IEC 9636-1 and in clause 4.
