zstd_is_error(9)

🌸 NAME 🌸

Hiii bestie, welcome to the Kernel API Manual 💖. This little icon is zstd_is_error — she tells you if a size_t function result is an error code. That’s the whole job. Slay.

✨ SYNOPSIS ✨

unsigned int zstd_is_error (size_t code );

🎀 ARGUMENTS 🎀

• code — the function result you’re checking for an error. Hand it over, bestie.

🦋 RETURN 🦋

Non-zero iff code is an error. Literally the entire vibe check: non-zero means error, periodt. No cap.
