✨ explain_putchar_or_die(3) ✨

okay bestie so you know how this is from the Library Functions Manual? yeah. it's a libexplain thing. let's get into it πŸ’…


🌸 NAME 🌸

explain_putchar_or_die β€” output of characters and report errors

like, it puts a char out there, and if that goes wrong it does NOT stay quiet about it. periodt.


πŸŽ€ SYNOPSIS πŸŽ€

#include <libexplain/putchar.h>
void explain_putchar_or_die(int c);

πŸ’– DESCRIPTION πŸ’–

So. The explain_putchar_or_die function is used to call the putchar(3) system call. that's the whole gig fr fr.

On failure an explanation will be printed to stderr, obtained from explain_putchar(3), and then the process terminates by calling exit(EXIT_FAILURE).

heads up: this thing does not do the graceful "return an error code and let you decide" vibe. if it fails, it prints the tea and then it ends the process. that's the "or_die" part, iykyk πŸ’€

This function is intended to be used in a fashion similar to the following example:

explain_putchar_or_die(c);
  • c β€” the c, exactly as to be passed to the putchar(3) system call. no notes. same c. ✨

Returns:

This function only returns on success. On failure, prints an explanation and exits.

so yeah: if you're still standing after the call, congrats, it worked 🫢
