Assertions

'''Include File(s):''' [http://hg.libsdl.org/SDL/file/default/include/SDL_assert.h SDL_assert.h]

Introduction

This category contains functions for managing assertions.

A fairly detailed discussion of the features of SDL_assert vs the standard assert() macro, and some technical explanation about how this is implemented can be found [http://web.archive.org/web/20190322035412/https://plus.google.com/103391075724026391227/posts/KzV6sLdALX7 in this Google+ post from Ryan].

SDL_ASSERT_LEVEL affects which assertions, if any, are processed during compiling based on which function was used to create the assertion (see functions below).

SDL_ASSERT_LEVEL can be defined in your project. If not otherwise set, SDL_ASSERT_LEVEL will default to level 2 for debug builds or level 1 for release builds.

The following table describes each SDL_ASSERT_LEVEL setting and the corresponding impact on the three SDL_assert functions:

'''SDL_ASSERT_LEVEL''' '''Description''' '''Function''' '''Function Status'''
<:>'''0''' all assertions disabled SDL_assert
SDL_assert_release
SDL_assert_paranoid
disabled

<:>'''1''' for release (default) SDL_assert

<:>'''3''' stringent for detailed checking SDL_assert
