zstd_cstream...ext_seq_prod(9)

✨ NAME ✨

okay so this is the zstd_cstream...ext_seq_prod(9) page from the Kernel API Manual, and the function is literally zstd_cstream_workspace_bound_with_ext_seq_prod — memory needed to initialize a zstd_cstream when using the block-level external sequence producer API. that’s the whole NAME section, and honestly it’s giving “very specific but iconic” 🎀✨

🌸 SYNOPSIS 🌸

size_t zstd_cstream_workspace_bound_with_ext_seq_prod (const
zstd_compression_parameters *cparams );

like, that’s the signature bestie — keep the const and the *cparams exactly where they are, no cap 🙈💅

🎀 ARGUMENTS 🎀

• cparams — the compression parameters to be used for compression. that’s it, that’s the argument, and yes she’s the const zstd_compression_parameters *cparams from the synopsis above 🫶

💖 RETURN 💖

A lower bound on the size of the workspace that is passed to zstd_init_cstream. so it’s giving lower-bound energy: the workspace size that gets passed to zstd_init_cstream, periodt 💫
