💖 NAME 💖

mysql_fetch_field_direct — returns a pointer to a MYSQL_FIELD structure. yes bestie that's literally the whole job description 💅

Oh also hi, this is from the MariaDB Connector/C manual, and it's the mysql_fetch_field_direct(3) page. Putting that up front so you know where you are 🫶

✨ SYNOPSIS ✨

#include <mysql.h>

MYSQL_FIELD * mysql_fetch_field_direct(MYSQL_RES * res,
                                       unsigned int fieldnr);

look at that signature. so clean. so demure. 🌸

🎀 DESCRIPTION 🎀

Okay so here's the vibe: this function hands you back a pointer to a MYSQL_FIELD structure, and that structure is packed with field info from whichever result set you point it at. it's giving "let me tell you everything about this one specific field" energy 👑

Parameter

  • res — a result set identifier, the kind you get back from mysql_store_result(3) or mysql_use_result(3). it's your ticket to the data, bestie 🎟️
  • fieldnr — the field number. and ngl this one has rules: it must be within the range from 0 to number of fields - 1. off-by-one will absolutely humble you 😭

Notes

  • The total number of fields? you can get that from mysql_field_count(). that's your cheat code for staying in range 🔥

🌈 RETURN VALUE 🌈

A pointer to a MYSQL_FIELD structure 🫶 … or NULL if you specified an invalid field number. so if you get NULL back, that's the universe telling you your fieldnr was not it 💀

okay that's the whole page, no notes, you ate 💅✨
