🌸 NAME 🌸

nerr_match 💅

✨ SYNOPSIS ✨

#include <util/neo_err.h>

int nerr_match (NEOERR *err, NERR_TYPE type);

🎀 ARGUMENTS 🎀

• err — the NEOERR that has an error. Yes, that one.
• type — the NEOERR type, as registered with nerr_register.

🦋 DESCRIPTION 🦋

okay so nerr_match is the bestie that walks the NEOERR chain and checks the error against one specific error type. In exception-speak? It’s literally the equivalent of "catch" — periodt.

Most of the time you can just compare a NEOERR against STATUS_OK, or just test for true if you’re checking for any error at all. Easy.
