ERR_ASPRINTF_ERROR_DATA(3)

💖 ERR_asprintf_error_data 💖

Okay bestie, welcome to the Library Functions Manual page for ERR_asprintf_error_data — yes, that’s the manual name folded in near the top, periodt. 💅

🎀 NAME 🎀

ERR_asprintf_error_data — record a LibreSSL error using a formatted string. ✨

✨ SYNOPSIS ✨

#include <openssl/err.h>

void
ERR_asprintf_error_data(char * format, ...);

🦋 DESCRIPTION 🦋

So ERR_asprintf_error_data builds a string using asprintf(3), and it calls asprintf(3) with the format and arguments you give it. The resulting string is then associated with the error code that was most recently added. 💖 If asprintf(3) fails, the string "malloc failed" is associated instead. No cap, that’s the fallback.

It’s intended to be used instead of the OpenSSL functions ERR_add_error_data() and ERR_add_error_vdata(). It’s giving replacement main character energy. 🦋

ERR_asprintf_error_data appeared in OpenBSD 5.6 and is available in all versions of LibreSSL. Iconic behavior, honestly. 👑
