zstd_cctx_workspace_bound(9)

hey bestie 💖 welcome to zstd_cctx_workspace_bound(9) from the Kernel API Manual. this is the page for the max memory needed to initialize a zstd_cctx — yes, the workspace-size check, and it's lowkey important. let's get into it ✨

💖 NAME 💖

zstd_cctx_workspace_bound — max memory needed to initialize a zstd_cctx. that's the whole name, and it ate 💅

✨ SYNOPSIS ✨

size_t zstd_cctx_workspace_bound (const zstd_compression_parameters
*parameters );

the signature is right there, character for character, bestie.

🎀 ARGUMENTS 🎀

• parameters — the compression parameters to be used. 👑

🦋 DESCRIPTION 🦋

okay so here's the tea: if multiple compression parameters might be used, the caller must call zstd_cctx_workspace_bound for each set of parameters and use the maximum size. must is doing a lot of work there — don't skip it, bestie. call it for every parameter set, then take the biggest size. no cap.

🌸 RETURN 🌸

A lower bound on the size of the workspace that is passed to zstd_init_cctx. that's the return value: the lower-bound workspace size, periodt.
