Detailed Description

All functions of the main API (Iup***) calls iup_assert to check the parameters.

The IUP main library must be recompiled with the IUP_ASSERT define to enable these checks. iup_assert is not called inside driver dependent functions nor in each control implementation, it is used only in the functions of the main API and in some utilities.

See iup_assert.h
