g2_addlocal.c(3)

🦋 g2_addlocal.c — like, the manual page, but make it make sense 💅

okay bestie, so this is a page from the Library Functions Manual, section 3, all about g2_addlocal.c. It lives in NCEPLIBS-g2c and honestly? It's giving "tiny function, huge responsibility." Let's get into it. ✨

👑 Function Documentation 👑

⭐ g2int g2_addlocal (unsigned char * cgrib, unsigned char * csec2, g2int lcsec2)

Adds a Local Use Section (Section 2) to a GRIB2 message. This function is used with routines g2_create(), g2_addgrid(), g2_addfield(), and g2_gribend() to create a complete GRIB2 message. So like, it's part of a whole ensemble cast — it does NOT work alone, periodt. 🌈

🎀 Parameters

• cgrib — Char array that contains the GRIB2 message to which section 2 should be added. Must be allocated large enough to store the entire GRIB2 message. (Yes bestie, large enough for the whole thing — don't be out here under-allocating, I'm begging. 😭)
• csec2 — Character array containing information to be added in Section 2.
• lcsec2 — Number of bytes of character array csec2 to be added to Section 2.

💜 Returns

> 0 = Current size of updated GRIB2 message.

And if it's not a happy number, it's one of these lil gremlins:

• G2_ADD_MSG_INIT — GRIB message was not initialized. Need to call routine gribcreate first.
• G2_ADD_MSG_COMPLETE — GRIB message already complete. Cannot add new section.
• G2_BAD_SEC_COUNTS — Sum of Section byte counts doesn't add to total byte count.
• G2_BAD_SEC — Previous Section was not 1 or 7.

📌 Note

The Local Use Section (Section 2) can only follow Section 1 or Section 7 in a GRIB2 message. It's picky, okay? Respect the order. 🙈
