✨ cdk_params — Cdk command-line parsing ✨

okay bestie, pull up a chair 🫶 this is the cdk_params page from the Library calls section of the Cdk manual, and it's literally the ✨command-line glow-up✨ for every Cdk utility and demo program out there. no cap.

🌸 NAME 🌸

cdk_params — Cdk command-line parsing 💅

---

🎀 SYNOPSIS 🎀

so first you gotta link it, like:

cc [ flag ... ] file ...  -lcdk [ library ... ]

then include the header, obviously:

#include <cdk.h>

and here's the whole friend group of functions 👑:

int CDKparamNumber (
               CDK_PARAMS *params,
               int option);

int CDKparamNumber2 (
               CDK_PARAMS *params,
               int option,
               int missing);

char * CDKparamString (
               CDK_PARAMS *params,
               int option);

char * CDKparamString2 (
               CDK_PARAMS *params,
               int option,
               const char *missing);

void CDKparseParams (
               int argc,
               char **argv,
               CDK_PARAMS *params,
               const char *options);

int CDKparsePosition (
               char *string);

int CDKparamValue (
               CDK_PARAMS * params,
               int option,
               int missing);

🦋 DESCRIPTION 🦋

so these are a set of functions used to implement the command-line utilities and demonstration programs for Cdk. the way that they don't just set the programs' options at initialization — instead they construct a simple database which holds the common parameters using CDKparseParams(). it's giving organized. it's giving main character energy. 💖

🌈 AVAILABLE FUNCTIONS 🌈

• CDKparamNumber — retrieves an integer (or boolean) option value from the parsed command-line. slay, a number, just for you ✨
• CDKparamNumber2 — retrieves an optional integer (or boolean) value from the parsed command-line. if the command line option is not present, the missing value is used. bestie's got a backup plan 🫶
• CDKparamString — retrieves a string option value from the parsed command-line. words! iconic 💅
• CDKparamString2 — retrieve an optional string option value from the parsed command-line. 🎀
• CDKparamValue — retrieve an integer (or boolean) option value from the parsed command-line. 🔥
• CDKparseParams — parse the given argc/argv command-line, with the options passed to getopt()'s 3rd parameter. yes, that getopt(), iykyk 👑
• CDKparsePosition — parse the string as one of CDK's positioning keywords, or an actual position. 🌸
