byte_rchr(3)

✨ byte_rchr(3) ✨

okay so bestie, we're in the Library Functions Manual today and the function on the menu is byte_rchr 💅 come sit with me

🌸 NAME 🌸

byte_rchr — searching for a byte inside a string, but like… from the back 🦋

🎀 SYNTAX 🎀

#include <libowfat/byte.h>

size_t byte_rchr(const char *haystack,size_t len,char needle);

yes the header is libowfat/byte.h, no you can't skip it, the compiler WILL throw hands 😭

💖 DESCRIPTION 💖

byte_chr returns the largest integer i between 0 and len-1 inclusive such that one[i] equals needle. 👑

if no such integer exists, byte_chr returns len. periodt.

also real talk — byte_rchr may read all bytes one[0], one[1], ..., one[len-1], even if not all the bytes are relevant to the answer. it's giving "reads the whole group chat even though you only needed one message" 📖✨

not me noticing the original page says byte_chr in these lines when the whole page is literally byte_rchr… anyway iykyk, i'm just the messenger 🫶
