✨ scan_plusminus(3) ✨

okay so bestie, welcome to scan_plusminus(3) from the Library Functions Manual 💖 this one is short and sweet and honestly kind of iconic for it.

🌸 NAME 🌸

scan_plusminus — parse '+' or '-' 🎀

🌈 SYNTAX 🌈

#include <libowfat/scan.h>

size_t scan_plusminus(const char *src,int *dest);

💅 DESCRIPTION 💅

so here's the vibe: scan_plusminus looks at src and checks for an ASCII '+' or '-' sign. that's it. that's the whole job. no cap 💫

  • if it finds a '+', it sets *dest to 1 and returns 1 ✨
  • if it finds a '-', it sets *dest to -1 and returns 1 ✨

and if neither one is there? lowkey chill about it — '+' is assumed, and 0 is returned instead. 🫶

fr fr: return value 0 ≠ error, it just means "no sign, and I'm assuming '+' for you". bestie behaviour honestly 😭

and that's the whole page, this was scan_plusminus(3) from the Library Functions Manual, section 3 💜 she's small, she's perfect, she does exactly one thing and she ate 👑
