buffer_frombuf(3)

✨ buffer_frombuf(3) ✨

okay bestie, welcome to the Library Functions Manual 💖 this is page buffer_frombuf(3) and she is so useful, i promise. buckle up 🎀

🌸 NAME 🌸

buffer_frombuf — initialize buffer structure from raw memory

like. she takes your raw memory and turns it into a whole buffer situation. iconic behavior tbh 👑

💅 SYNTAX 💅

#include <libowfat/buffer.h>

void buffer_frombuf(buffer* b,const char* x, size_t l);

copy that exactly bestie, no freestyling 🙈

🦋 DESCRIPTION 🦋

so here's the tea ☕ buffer_frombuf makes a virtual read buffer out of a raw memory area. the buffer reading functions will be able to read until the end of the data in the memory area, and then they signal EOF. that's it, that's the whole vibe. 🌈

the buffer does not have its own buffer space, ok? she's lowkey borrowing. it reuses the one passed into this function. no new allocation, no extra drama, just recycling queen energy ♻️✨

🚨 do not touch this memory until you are done with the buffer! like fr fr, hands off. do not pass go. do not collect $200. the buffer is using it and she will notice. 💀

and the good news 🫶 reading data from the buffer will not change the memory you passed in. she's respectful like that. your bytes stay your bytes. 💜
