💖 simpack.c(3) 💖

okay bestie, welcome to the Library Functions Manual corner of the internet, because today we're talking about simpack.c — the little file that does Big Things. grab a strawberry 🍓, we're packing data fields.

✨ NAME ✨

simpack.c — Pack a data field using the simple packing algorithm.

like. that's it. that's the whole job. and she does it flawlessly. periodt. 💅

🌸 SYNOPSIS 🌸

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

🎀 Functions

  • void simpack (float *fld, g2int ndpts, g2int *idrstmpl, unsigned char *cpack, g2int *lcpack) — Packs a data field using the simple packing algorithm.

💜 Detailed Description 💜

👑 Function Documentation 👑

💫 void simpack (float * fld, g2int ndpts, g2int * idrstmpl, unsigned char * cpack, g2int * lcpack)

Packs a data field using the simple packing algorithm. no cap, this function also fills in GRIB2 Data Representation Template 5.0 with the appropriate values. she multitasks. she's giving main character energy. ✨

🦋 Parameters

  • fld — Contains the data values to pack. the raw material, bestie.
  • ndpts — The number of data values in array fld. she needs a headcount before the party starts.
  • idrstmpl — Contains the array of values for [Data Representation Template 5.0](https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_temp5-0.shtml). (https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_temp5-0.shtml — yes I'm dropping the link text, it's literally the template, iykyk.)
    • 0 — Reference value - ignored on input - set by simpack routine. so don't bother passing anything, she's overwriting it anyway 🙈
    • 1 — Binary Scale Factor - unchanged from input. she respects your choices here.
    • 2 — Decimal Scale Factor - unchanged from input. also untouched. icon behavior.
    • 3 — Number of bits used to pack data, if value is > 0 and <= 31. If this input value is 0 or outside above range then the num of bits is calculated based on given data and scale factors. so like — give her a valid number and she uses it, give her nonsense and she does the math herself. adaptable queen. 💅
    • 4 — Original field type - currently ignored on input. Data values assumed to be reals. Set to 0 by simpack routine. lowkey ignored but highkey set to 0. 💀
  • cpack — The packed data field. this is the glow-up result, the finished fit.
  • lcpack — length of packed field starting at cpack. the measurements, bestie. 📏
