GXValidateInk

You can use the GXValidateInk function to check the parameters of an ink object.

void GXValidateInk(gxInk target);

target

A reference to an ink object to be validated.

DESCRIPTION

The GXValidateInk function checks parameters for the color, transfer mode, attributes, owner count, and tag list properties for all ink objects. In addition, this function checks any internal caches built for the ink. If one or more of the parameters are not valid, QuickDraw GX posts a validation error.

This function is not operational in the non-debugging version of QuickDraw GX.
