GXValidateTag

You can use the GXValidateTag function to check the parameters of a tag object.

void GXValidateTag(gxTag target);

target

A reference to a tag object to be validated.

DESCRIPTION

The GXValidateTag function checks the parameters for the tag type, size, contents, and owner count properties for all tag objects. In addition, this function checks any internal caches built for the tag. 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.
