Detailed Description

Some assert-definintions, and a debug-printf using a MessageBox.

Use asserts where you want to assert(sic!) a condition, and if it it's not ok, there's no use to continue execution. All Ass* 'functions' here will exit() after displaying a message - so this is for fatal errors, such as internal inconstencies, end of memory conditions, unexpected and un-manageable Win32-API returns etc.

Macros ASSCHK, ASSAPI and ASSPTR are used to actually call the function so as to get the correct file and line into the message produced.
