πŸ’… reverse_memcmp

okay bestie, so this whole page is reverse_memcmp from the kernel API manual (9), and it's basically memcmp but walking backwards. iconic behaviour honestly. let's get into it ✨


🌸 SYNOPSIS

int reverse_memcmp (const void *cs , const void *ct , size_t count );

that's the whole signature, no notes. πŸŽ€


πŸ¦‹ ARGUMENTS

  • cs β€” one area of memory. like, a block of bytes, the first one, your main character block πŸ’–
  • ct β€” another area of memory. the other block. the rival. the comparison partner 🌈
  • count β€” the size of the area. how many bytes we're looking at, no cap πŸ’…

πŸ”₯ DESCRIPTION

so this is a cut'n'paste from the original memcmp (peep lib/string.c if you wanna see the og πŸ‘€), just with minimal modifications. that's it, that's the lore. it compares two areas of memory, but in reverse order β€” hence the name, iykyk 🧚

fr fr, "minimal modifications" is the whole description. the kernel devs said copy, paste, tweak, slay, periodt. πŸ’€

⭐ SEE ALSO

  • Kernel file ./drivers/net/wireless/ath/wil6210/txrx.c β€” this is where the vibes live, go look 🫢

aaaand that's the page bestie!! πŸŽ€ this little gem comes from source ./drivers/net/wireless/ath/wil..., dated October 2026, and it lives in the manual as reverse_memcmp(9) β€” go forth and compare in reverse, you absolute icon πŸ‘‘πŸ’œ
