🌸 readclose(3) 🌸

okay so bestie, welcome to the Library Functions Manual — manual name folded in, no cap — and today's main character is readclose(3). she's giving "read a whole file into a stralloc" energy and we are obsessed. 💖✨

✨ NAME ✨

readclose — read a whole file into a stralloc 🫶

📜 SYNTAX 📜

#include <libowfat/readclose.h>

int readclose(int fd,stralloc* sa,size_t bufsize);

💅 DESCRIPTION 💅

so readclose reads the whole content into the stralloc sa. yes, the whole content, she's not doing half measures. 💀

the file is read in chunks of bufsize bytes size. that's the chunk size, periodt. 🎀

if everything worked fine, readclose returns 0. slay. ✅

on error, readclose returns -1 and sets errno appropriately. so if it's not giving 0, the errno tea is right there, bestie. 🚨
