πΈ range_end_overflows_t(9) πΈ
ok so this is a page from the Kernel API Manual (yes, the kernel has lore, and yes it's giving β¨documentationβ¨) and today's main character is range_end_overflows_t. buckle up bestie, it's short and sweet π
π NAME π
range_end_overflows_t β the vibe check that tells you if a range's endpoint is out of bounds π
β¨ SYNOPSIS β¨
range_end_overflows_t (type , start , size , max );
that's it. that's the whole call. iconique π«Ά
π¦ ARGUMENTS π¦
typeβ the data type to use, bestie. it's the whole personality of this macro ngl.startβ where the range starts. the beginning. the origin story π±sizeβ how big the range is. how much we're working with πͺmaxβ the exclusive upper boundary. note that word, it's doing so much heavy lifting here π
π DESCRIPTION π
ok so real talk: this is exactly the same as range_end_overflows, except it forces the parameters to type. literally that's the whole difference. same brain, extra commitment π₯
like, range_end_overflows is out here being all flexible and this one is like "no. we're doing type. all of us. together." and honestly? respect. periodt π
π RETURN π
it returns true if the endpoint exceeds the boundary. that's it, that's the answer. no shades of gray, just true or not-true. slay π
π SEE ALSO π

not me listing all 31 of themβ¦ iykyk π but fr fr they're all your besties too, go say hi π«Ά
β that's the whole page bestie, go forth and check those endpoints, no cap π
kisses, from ./include/linux π β this one dropped October 2026, catch you on the next manpage πβ¨
