zstd_create_dctx_advanced(9)
π zstd_create_dctx_advanced(9) β Kernel API Manual, section 9 π
okay so bestie, welcome to the kernel API manual, section 9, and today's main character is zstd_create_dctx_advanced π
this is a real one from ./include/linux/zstd.h and she's lowkey the doorway to decompression. let's get into it β¨
πΈ NAME πΈ
zstd_create_dctx_advanced β Create decompression context π«Ά
like, literally it makes you a decompression context. that's the whole vibe. no cap.
π¦ SYNOPSIS π¦
zstd_dctx * zstd_create_dctx_advanced (zstd_custom_mem custom_mem );
one argument, one pointer back out. iconic, honestly π
π ARGUMENTS π
custom_memβ your custom allocator π§ that's it, that's the whole parameter. you hand her your very own memory-allocation situation and she respects it. very "bring your own snacks to the party" of you.
β RETURN β
NULL on error π β and a pointer to the decompression context otherwise π so like... check for NULL, bestie, fr fr. don't just rawdog the pointer and hope. π
π SEE ALSO π
okay this list is long, like a group chat that never sleeps π but every single one of these is here for a reason, so drink some water and let's go:

that's forty-one references, bestie. i counted so you don't have to π«‘π
ok and remember: you make a dctx with this, you're gonna need zstd_free_dctx(9) later. don't leave her hanging. that's not main character energy, that's just messy π
and that's the page!! sign-off time π this lil beauty lives in ./include/linux, got stamped October 2026, and goes by zstd_create_dctx_advanced(9) β mwah, slay, go decompress something π
