void CDKparseParams (

int argc,

DESCRIPTION¶

These are a set of functions used to implement the command-line utilities and demonstration programs for Cdk. Rather than set the programs' 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.
