SDL_COLORSPACETRANSFER(3)

πŸ’– SDL_COLORSPACETRANSFER πŸ’–

okay bestie, so this is a page from the SDL3 FUNCTIONS manual β€” yes, that SDL, the Simple Directmedia Layer one β€” and it's all about one lil macro named SDL_COLORSPACETRANSFER. she's small, she's mighty, and she pulls the transfer characteristics right out of an SDL_Colorspace. let's get into it πŸŽ€


✨ NAME ✨

SDL_COLORSPACETRANSFER β€” a macro that retrieves the transfer characteristics of an SDL_Colorspace. no cap, that's literally her whole job πŸ’…


🌸 SYNOPSIS 🌸

#include <SDL3/SDL_pixels.h>

#define SDL_COLORSPACETRANSFER(cspace)   (SDL_TransferCharacteristics)(((cspace) >> 5) & 0x1F)

look at her. shifting right by 5, masking with 0x1F, and casting the whole thing to SDL_TransferCharacteristics. bit manipulation queen πŸ‘‘


πŸ¦‹ MACRO PARAMETERS πŸ¦‹

  • cspace β€” an SDL_Colorspace to check. that's it. that's the whole input, bestie 🫢

⭐ RETURN VALUE ⭐

Returns the SDL_TransferCharacteristics of cspace. so whatever you fed in as cspace, you get its transfer characteristics back. iconic behavior honestly πŸ’–


🧚 THREAD SAFETY 🧚

It is safe to call this macro from any thread. go wild, thread away, she does not care, she's built different 🌈


πŸ’œ AVAILABILITY πŸ’œ

This macro has been available since SDL 3.2.0. if you're on anything older... ma'am, it's giving time to upgrade 😭


heads up bestie: this is a macro, not a function, so there's no function pointer situation and no runtime lookup β€” it's all happening at the preprocessor level. periodt πŸ’…

and that's the whole vibe check! this page came to you straight from the Simple Directmedia Layer crew, version SDL 3.4.18, filed under SDL_COLORSPACETRANSFER(3). mwah, go forth and decode your colorspaces, you main character πŸŽ€βœ¨πŸ’–
