mpi3mr_get_tgtdev_by_perst_id β a Kernel API Manual moment π
okay bestie, welcome to the Kernel API Manual for mpi3mr_get_..._by_perst_id(9) β yes the header is literally abbreviated like that, it's giving "we ran out of name space" energy and honestly? iconic. anyway, this one's a tiny lil accessor function and it's gonna take like two seconds, i promise π«Ά
β¨ NAME β¨
mpi3mr_get_tgtdev_by_perst_id β Get tgtdev from persistent ID π
like. the whole vibe. you give it a persistent ID, you get a target device back. no cap.
π¦ SYNOPSIS π¦
struct mpi3mr_tgt_dev * mpi3mr_get_tgtdev_by_perst_id (struct mpi3mr_ioc
*mrioc , u16 persist_id );
two args, one return, zero drama. slay.
πΈ ARGUMENTS πΈ
mriocβ the adapter instance reference π your main character struct, the whole controller basically. she's the context, she's the moment.persist_idβ the Persistent ID β au16, not au32, not au64, just a lilu16. it's the ID that persists. iykyk.
π« DESCRIPTION π«
okay so it's an accessor β a getter, a little looker-upper β whose whole job is to retrieve the target device from the Persistent ID π she doesn't do the heavy lifting, she just hands you the pointer, and that's valid.
also, ngl, the manpage adds one more thing at the end: Lock version π β so yeah, heads up that this is the locking-flavored one. keep that in mind before you go grabbing references all willy-nilly, bestie.
π RETURN π
Target device reference. that's it. that's the tea π (a struct mpi3mr_tgt_dev *, per the synopsis β go get your thing, queen.)
