errmsg_iam(3)

✨ NAME ✨

errmsg_iam — bestie, this is the lil function that tells the errmsg library what your program is actually called 💅

🌸 SYNTAX 🌸

#include <libowfat/errmsg.h>

void errmsg_iam(const char *progname);

🎀 DESCRIPTION 🎀

okay so. you call this function to set the program name. that's it. that's the whole job. and it eats it UP every single time 🫶

the vibe is: you hit this thing usually right at the very start of main(), and you hand it argv[0] as the argument. like, first line of your program, before anything else gets to be dramatic. very main character energy of you ✨

and why do we care?? because batch processing, babes!! when your stuff is running in a big ol' batch and errors start flying everywhere, the observer needs to be able to tell which program the error message came from 😭🙈 without it, every error is just an anonymous screaming ghost and nobody knows who did it. with it, everyone knows exactly whose fault it is. iconic. periodt. 👑

ngl, it's one line of code and it saves the whole batch run. lowkey the most underrated function in the whole library, fr fr 💖
