✨ misspack.c(3) ✨

okay bestie, sit down, hydrate, because we're about to talk about the absolute moment that is misspack.c from the Library Functions Manual. this is a C library function page, she's giving very much "quiet legend in a big GRIB2 pipeline" energy, and i am obsessed. 🫶

🌸 NAME 🌸

misspack.c — pack a data field using a complex packing algorithm, as defined in the GRIB2 documentation. periodt. 💅

---

🦋 SYNOPSIS 🦋

so first things first, you gotta bring the right friends to the party:

#include 'grib2_int.h'
#include <math.h>
#include <stdlib.h>

✨ Functions ✨

and then, the main character herself:

void misspack (float *fld, g2int ndpts, g2int idrsnum, g2int *idrstmpl,
    unsigned char *cpack, g2int *lcpack)

what does she do? she packs a data field using a complex packing algorithm. that's the whole vibe. 😌

💜 Detailed Description 💜

👑 Function Documentation 👑

💖 void misspack (float * fld, g2int ndpts, g2int idrsnum, g2int * idrstmpl, unsigned char * cpack, g2int * lcpack) 💖

pack a data field using a complex packing algorithm. and listen, this function is flexible like that — she supports GRIB2 complex packing templates with or without spatial differences. (see Template 5.2 and Template 5.3, bestie, go look, i'll wait 💅).

this function fills in GRIB2 Data Representation template arrays with the appropriate values. she's doing the homework so you don't have to. 🎀

🌈 Parameters 🌈

• fld — contains the data values to pack.
• ndpts — the number of data values in array fld.
• idrsnum — Data Representation Template number. must equal 2 or 3. not 2.5, not 4, not vibes. 2 or 3. 🚨
• idrstmpl — contains the array of values for Data Representation Template 5.2 or 5.3.
  • 0 Reference value — ignored on input, set by the misspack routine. so don't bother, she handles it. ✨
  • 1 Binary Scale Factor — used on input.
  • 2 Decimal Scale Factor — used on input.
  • 6 Missing value management.
  • 7 Primary missing value.
  • 8 Secondary missing value.
  • 16 Order of Spatial Differencing (1 or 2).
• cpack — the packed data field (character*1 array).
• lcpack — length of packed field cpack.

and that's the whole page, bestie!! this diva shipped in NCEPLIBS-g2c, Version 2.3.0, and the page itself is dated misspack.c(3) — she ate and left no crumbs. mwah. 💋✨🦋🌸💜🎀👑
