System Information: Obtaining Device Information

This tutorial demonstrates how you can obtain device information, such as platform version, device model, and supported device features.

Warm-up

Become familiar with the System Information API basics by learning about:

Getting the Device Model Name
Get the model name of the device.
Checking Whether a Camera is Provided
Check whether the device provides a camera.

Getting the Device Model Name

To get the device model name:

To use the device-specific information-related features of the System Information API (in mobile and wearable applications), include the <system_info.h> header file in your application:
```
#include <system_info.h>
```

Device-specific information consists of "key, value" pairs. To get the device model name, use the http://tizen.org/system/model_name key.

The type of the value is String, which means that the system_info_get_platform_string() function is used for the information. The value of the key must be released by the free() function.

void func(void)
{
   char *value;
   int ret;

   ret = system_info_get_platform_string("tizen.org/system/model_name", &value);
   if (ret != SYSTEM_INFO_ERROR_NONE) 
   {
      // Error handling
      return;
   }

   dlog_print(DLOG_INFO, LOG_TAG, "Model name: %s", value);

   free(value); // Release after use 
}

Checking Whether a Camera is Provided

To check whether a camera is provided:

To use the device-specific information-related features of the System Information API (in mobile and wearable applications), include the <system_info.h> header file in your application:
```
#include <system_info.h>
```

To check whether the device provides any kind of a camera, use the http://tizen.org/feature/camera key.

The type of the value is bool, which means that the system_info_get_platform_bool() function is used for the information.

#include <stdbool.h>

void func(void)
{
   bool value;
   int ret;

   ret = system_info_get_platform_bool("tizen.org/feature/camera", &value);
   if (ret != SYSTEM_INFO_ERROR_NONE) 
   {
      // Error handling
      return;
   }

   dlog_print(DLOG_INFO, LOG_TAG, "Camera: %s", value ? "Supported" : "Not supported");
}
