✨ specpack.c — the manual page bestie ✨

okay so you found your way into specpack.c(3), part of the Library Functions Manual 🎀 no gatekeeping here, let's get into it.

🌸 NAME 🌸

specpack.c — Pack a spectral data field using the complex packing algorithm for spherical harmonic data.

like it literally does what it says on the tin, and the tin is very specific 💅

🌈 SYNOPSIS 🌈

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

🧚 Functions 🧚

  • void specpack (float *fld, g2int ndpts, g2int JJ, g2int KK, g2int MM, g2int *idrstmpl, unsigned char *cpack, g2int *lcpack) — Pack a spectral data field using the complex packing algorithm for spherical harmonic data as defined in the GRIB2 Data Representation Template 5.51.

💖 Detailed Description 💖

Pack a spectral data field using the complex packing algorithm for spherical harmonic data. that's the whole vibe, no notes 🫶

👑 Function Documentation 👑

✨ void specpack (float * fld, g2int ndpts, g2int JJ, g2int KK, g2int MM, g2int * idrstmpl, unsigned char * cpack, g2int * lcpack) ✨

Pack a spectral data field using the complex packing algorithm for spherical harmonic data as defined in the GRIB2 Data Representation Template 5.51.

🍓 Parameters 🍓

  • fld — Contains the data values to be packed.
  • ndpts — The number of data values to pack.
  • JJ — J - pentagonal resolution parameter.
  • KK — K - pentagonal resolution parameter.
  • MM — M - pentagonal resolution parameter.
  • idrstmpl — Contains the array of 10 values for [Data Representation Template 5.51](https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_temp5-51.shtml).
  • cpack — Pointer that gets the packed data field. Must be allocated by caller.
  • lcpack — length of packed field cpack.
🚨 bestie listen — cpack is your job to allocate. the function is not gonna do it for you, she's not your mom 😭

aaaand that's the page! this whole thing is living under NCEPLIBS-g2c, Version 2.3.0, filed as specpack.c(3) 💖 go pack some spectral data, you got this 🫶✨
