SYNOPSIS

#include <libkyedid.h>

extern char* kdk_edid_get_resolution(char *name);

Link with -lkyedid.

Detailed Description

The main function of the interface is to obtain the resolution of the screen.

The argument name is the current interface of the screen.

RETURN VALUE

On success, returns the resolution of type char*; The returned string needs to be released by free

On error, return NULL.

EXAMPLES

#include "libkyedid.h"
#include <stdio.h>
#include <stdlib.h>
int main()
{
    char** name = kdk_edid_get_interface();
    size_t count = 0;
    while (name[count])
    {
        printf("当前接口 = %s0, name[count]);
        float gamma = kdk_edid_get_gamma(name[count]);
        printf("gamma = %0.2f0, gamma);
        float size = kdk_edid_get_size(name[count]);
        printf("size = %0.1f0, size);
        char *max_resolution = kdk_edid_get_max_resolution(name[count]);
        printf("max_resolution = %s0, max_resolution);
        free(max_resolution);
        char *model = kdk_edid_get_model(name[count]);
        printf("model = %s0, model);
        free(model);
        char *area = kdk_edid_get_visible_area(name[count]);
        printf("area = %s0, area);
        free(area);

        char *resolution = kdk_edid_get_resolution(name[count]);
        printf("resolution = %s0, resolution);
        free(resolution);
        char *ratio = kdk_edid_get_ratio(name[count]);
        printf("ratio = %s0, ratio);
        free(ratio);
        char *character = kdk_edid_get_character(name[count]);
        printf("character = %s0, character);
        free(character);
        printf("---------------------------------------0);
