Setting and Getting Validation Options and Errors

This section describes the functions that control QuickDraw GX validation. QuickDraw GX validation checks public and internal function parameters to ensure that they are valid. You can use validation functions and flag options to check types, structures, all objects, memory, and specific objects.

When validation error checking is on, QuickDraw GX may post the validation errors listed in the section "Debugging Version" in the chapter "Errors, Warnings, and Notices."
