range_str2inbuf(3)

💖 NAME 💖

okay so bestie, this is range_str2inbuf — she does a range check for a string in a buffer. no cap. ✨

✨ SYNTAX ✨

#include <libowfat/rangecheck.h>

int range_str2inbuf(const void* buf,size_t len,const void* string);

🦋 DESCRIPTION 🦋

range_str2inbuf checks that the zero terminated UTF-16-string starting at string starts and ends within the buffer buf[0..len-1]. she's basically making sure your string is not out here wandering into the void, periodt. 💅

If the string is not 0-terminated but the length is known beforehand, use range_arrayinbuf instead. that's the sister function for when you already know how long it is, iykyk. 🫶

🌸 RETURN VALUE 🌸

• If the buffer is implausible (buf is NULL or buf+len has an integer overflow), return 0. that's a hard no. 💀
• If string points before or after the buffer, return 0. she's outside the function's assigned area, not invited. 🙈
• If there is no zero terminator within the buffer, return 0. no end in sight? not today. 😭
• Otherwise, return 1. slay! she passed the vibe check. 👑
