Retrieving a user's selection

In order to retrieve the user's selection at run-time, you must first query for the Default<optionname> entry. Its .value member defines the selection made. With the value of the .value member search for the selection entry and then you have access to all members.

const char *economode_value;
struct caps_ppd_option *default_economode_option;
struct caps_ppd_option *economode_option;
 
default_economode_option = caps_ppd_option_get(job->ppd_options, "DefaultEconomode");
economode_option = caps_pp_job_value_get(job->ppd_options, "Economode", default_economode_option->value);
 
economode_value = economode_option->value; // success

Another way would be to retrieve the "DefaultEconomode" selection and use its value to search in your original data (e.g. the econo_mode_selections array shown a few lines above) for all required values.

But there is a convenience function available which does the complicated part for you:

const char *economode_value;
 
economode_value = caps_pp_job_choice_get(job, "EconoMode"); // success
