π« ldm_parse_tocblock(9) π«
okay so bestie, welcome to the Kernel API Manual π β this one's a single little function from the kernel's LDM (that's Logical Disk Manager, iykyk) partition code, and it's honestly so straightforward it's giving main character energy. Let's get into it β¨
πΈ NAME πΈ
ldm_parse_tocblock β Read the LDM Database TOCBLOCK structure π«Ά
π¦ SYNOPSIS π¦
bool ldm_parse_tocblock (const u8 *data , struct tocblock *toc );
like, that's the whole vibe. one call, two args, one bool back π
π ARGUMENTS π
dataβ the raw database TOCBLOCK structure, freshly loaded off the device. literally the bytes straight from the disk, no cap πtocβ the in-memorytocstructure where the parsed info gets handed back to you. it's your lil output basket π§Ίβ¨
π₯ DESCRIPTION π₯
So what does it do? It parses the LDM Database TOCBLOCK (that's table of contents, bestie β yes, the boring-sounding one, but it's important π) structure that you handed in via data, and it sets up the in-memory tocblock structure toc with all the info it pulled out. simple as that, and it ate π
N.B. β οΈ the*_startand*_sizevalues that come back to you intocare not range-checked. like, at all. so pls don't just trust them blindly, okay? that's on you, not on this function π no cap, this is a real caveat, do not sleep on it.
π RETURN π
(nothing listed here in the original β the return type up in the synopsis is bool, and that's all the docs give us bestie, don't @ me π)
π SEE ALSO π
Kernel file ./block/partitions/ldm.c β plus the whole friend group of LDM helpers, all here for you π«Άβ¨
