cdk_params(3)						     Library Functions Manual						     cdk_params(3)

NAME

       cdk_params - Cdk command-line parsing

SYNOPSIS

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

       #include <cdk.h>

       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,
		      char *missing);

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

       int CDKparsePosition (
		      char *string);

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

DESCRIPTION

       These  are  a  set  of functions used to implement the command-line utilities and demonstration programs for Cdk.  Rather than set the pro-
       grams' options at initialization, they construct a simple database which holds the common parameters using CDKparseParams().

AVAILABLE FUNCTIONS

       CDKparamNumber
	    Retrieves an integer (or boolean) option value from the parsed command-line.

       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.

       CDKparamString
	    Retrieves a string option value from the parsed command-line.

       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.

       CDKparsePosition
	    Parse the string as one of CDK's positioning keywords, or an actual position.
