🎀 fileread() — reads file into buffer 🎀

okay so bestie, welcome to FILEREAD(3) from Schily´s LIBRARY FUNCTIONS. this is the whole vibe: read bytes from a file straight into your buffer. let's go 💅

✨ NAME ✨

fileread() - reads file into buffer

🦋 SYNOPSIS 🦋

int fileread(f,buf,size)
FILE *f;
char *buf;
int size;

🌸 DESCRIPTION 🌸

okay so fileread() reads up to size bytes from the file into buf. the number actually read may be smaller if end-of-file is reached. the file pointer (implied) is left pointing to one past the last character read. no cap, that's the whole behavior. 🫶

💖 RETURNS 💖

• > 0 — the number of bytes actually read.
• = 0 — file was at end-of-file.
• < 0 — error code.

it returns the number of bytes actually read or an error code. periodt.

🔥 NOTES 🔥

bestie, listen: the buffer must be at least size long. if reading from a "raw" device, size must be a multiple of 512.
