KDK_SYSTEM_GET_RESOLVING_POWER(3)                     Library Functions Manual

NAME
       kdk_system_get_resolving_power -
       <?><?><?><?><?><?><?><?><?><?>,<?><?><?>,<?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkysysinfo.h>

       extern char** kdk_system_get_resolving_power();

       Link with -lkysysinfo.

Detailed Description
       The main function of the interface is to obtain the current display
       screen of the system, the resolution, the resolution supported by the
       system.

RETURN VALUE
       On success, returns a list of resolution information of type char**,
       ending with a NULL character; Generated by alloc and needs to be
       recycled by kdk_resolving_freeall

       On error, return NULL.

EXAMPLES
       #include <libkysysinfo.h>
       #include <stdio.h>
       #include <stdlib.h>
