Description

PINVL sets the valuator device to application-specific values.  This function accepts the echo area in a 4-component list of x- and y-coordinates, in device coordinates.  The order of the list components is XMIN < XMAX, YMIN < YMAX.  The z-components of a previously specified echo volume remain unchanged. 

When an application calls PINVL, the workstation surface cannot contain the valuator device’s prompt.  To remove an existing prompt from the surface, call the PSVLM function and place the device in request mode. 

The size and contents of the data record depend on the prompt and echo type you specify.  If the size or contents of the data record does not match the requirements of your chosen prompt and echo type, Digital PHIGS generates an error. 

See Valuator-Class PETs for information on valuator-class prompt and echo types.
