relay_file_read_end_pos(9)
π relay_file_read_end_pos(9) β the glowed-up version
okay so real talk, this is a page from the Kernel API Manual (yes, section 9, the fancy section) and it's about relay_file_read_end_pos. bestie. it's a whole function that figures out your new read position. that's the vibe. it's giving "where do we even go from here" but make it kernel-level. π¦
β¨ NAME β¨
relay_file_read_end_pos β literally just returns the new read position π no cap, that's the whole job.
πΈ SYNOPSIS πΈ
size_t relay_file_read_end_pos (struct rchan_buf *buf , size_t read_pos
, size_t count );
look at her. three arguments, one size_t coming back. main character energy fr fr β¨
π ARGUMENTS π
bufβ the relay channel buffer π«Ά like, the actual buffer we're chillin' in.read_posβ the file read position. yes. where you're reading from. iconic.countβ how many bytes are about to be read π the number of bytes to be read, periodt.
π₯ SEE ALSO π₯
so this is the part where the manpage just dumps the entire friend group on you π and ngl you should respect it, because it's the full circle of relay-file life. every single one, no skipping, iykyk:

like, that's the whole squad π§ the start-pos one is right there at the end being all mysterious and complementary. obsessed. π
heads up bestie: that list is a list of other pages to go read, not extra behaviour of this function. don't go inventing lore π
β aaaand that's the page!! this lil' icon lives in ./kernel, dated October 2026, and it's serving relay_file_read_end_pos(9) realness from the Kernel API Manual. slay, go read your relay buffers, mwah ππ
