KDK_PACKAGE_GET_PACKAGELIST(3)                        Library Functions Manual

NAME
       kdk_package_get_packagelist - <?><?><?><?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkypackages.h>

       extern kdk_package_list* kdk_package_get_packagelist();

       Link with -lkypackage.

Detailed Description
       The main function of the interface is to obtain a list of all packages
       in the system.

RETURN VALUE
       On success, returns a pointer to a kdk_package_list structure
       containing gateway information.

       The kdk_package_list structure is defined in <libkypackages.h> as
       follows:

                   typedef struct {
                       unsigned int nums;
                       kdk_package_t **list;
                   }kdk_package_list;

                   typedef struct _kdk_package_t{
                       char *name;     // <?><?>
                       char *version;  // <?><?><?>
                       char *section;  // <?><?><?>
                       char *status;   // <?><?>
                       unsigned long size_kb;   // <?><?><?>
                       struct _kdk_package_t **depends; // <?><?><?>
                   }kdk_package_t;

       On error, return NULL.

EXAMPLES
       #include "libkypackages.h"
       #include <stdio.h>

       static void print_package(kdk_package_t *package)
       {
           printf("<?><?><?>%s", package->name);
           printf("<?><?><?><?>%s", package->version);
           printf("<?><?><?><?>%s", package->section);
           printf("<?><?><?><?>%s", package->status);
           printf("<?><?><?><?>%lu0, package->size_kb);
       }

       int main()
       {
           kdk_package_list *list = kdk_package_get_packagelist();
           printf("<?><?><?><?><?>%u<?><?><?><?>0, list->nums);
           for (size_t i = 0; i < list->nums; i ++)
           {
               print_package(list->list[i]);
           }
           kdk_package_free_packagelist(list);

           printf("Evolution<?><?><?><?><?>%s0, kdk_package_is_installed("evolution", NULL) == 1 ? "<?>" : "<?>");
           char *version = kdk_package_get_version("evolution");
           printf("Evolution<?><?><?><?>%s0, version);
           free(version);

           return 0;
       }
