You can use the GXValidateGraphicsClient function to check the parameters of a graphics client object.

void GXValidateGraphicsClient(gxGraphicsClient target);

target

A reference to a graphics client object to be validated.

DESCRIPTION

The GXValidateGraphicsClient checks all parameters for all properties of a graphics client object. In addition, this function checks any internal caches built for the graphics client. 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.
