Header File

Syntax

typedef struct SDL_version
{
    Uint8 major;        /**< major version */
    Uint8 minor;        /**< minor version */
    Uint8 patch;        /**< update version */
} SDL_version;

Remarks

Represents the library's version as three levels: major revision (increments with massive changes, additions, and enhancements), minor revision (increments with backwards-compatible changes to the major revision), and patchlevel (increments with fixes to the minor revision).

Code Examples

SDL_version compiled;
SDL_version linked;
