Querying SDL Version (SDL_version.h)
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: 1.3.0
There are four (4) macros green
that apply to this header.
This macro gathers information from SDL_MAJOR_VERSION, SDL_MINOR_VERSION, AND SDL_PATCHLEVEL (#defines) and fills the structure SDL_version with that information.
- A minor macro that converts version numbers into a numeric value.
- A minor macro that produces the current SDL version number (major.minor.patchlevel)
- A minor macro that confirms whether a program was compiled with a version no older than the specified version.
