Querying SDL Version

Include File(s): SDL_version.h

Introduction

These functions are used to collect or display information about the version of SDL that is currently being used by the program.

The version number consists of three segments (X.Y.Z)
- X = Major Version, which increments with massive changes, additions, and enhancements
- Y = Minor Version, which increments with backwards-compatible changes to the major revision
- Z = Patchlevel, which increments with fixes to the minor revision
Example: The current version is 1.3.0

Here are macros (green

) that are useful in dealing with version information.

SDL_VERSION
- This macro gathers information from SDL_MAJOR_VERSION, SDL_MINOR_VERSION, AND SDL_PATCHLEVEL (#defines) and fills the structure SDL_version with that information.
SDL_VERSIONNUM
- A macro that converts version numbers into a numeric value.
SDL_COMPILEDVERSION
- A macro that produces the current SDL version number (major.minor.patchlevel)
SDL_VERSION_ATLEAST
- A macro that confirms whether a program was compiled with a version no older than the specified version.
