## Introduction<a name="section11660541593"></a>

The resource management module, namely, resmgr, provides the function of loading multi-language GUI resources for applications, for example, displaying the application names or icons specific to a certain language.

## Directory Structure<a name="section1844145112017"></a>

The directory structure for the resource management module is as follows:

```
/base/global/
├── resource_management_lite                # Code repository for the resource management module
│   ├──  frameworks                         # Core code of the resource management module
│   │   ├── resource_management_lite        # Core code for resource parsing
│   │   │   ├── include                     # Header files of the resource management module
│   │   │   ├── src                         # Implementation code of the resource management module
│   │   │   └── test                        # Test code
│   ├──  interfaces                         # APIs of the resource management module
│   │   └── inner_api                       # APIs of the resource management module for internal subsystems
```

## Usage<a name="section17235135618274"></a>

Call the  **GLOBAL\_GetValueById**  API to obtain the resource information of the application.

```
#include <stdint.h>
#include <stdio.h>
#include "global.h"

uint32_t id = 0x16777216;
char *values = NULL;
int32_t re = GLOBAL_GetValueById(id, "/system/data/resources.index", &values); // Obtain the resource of a specified application and write the resource to values.
std::cout << values << std::endl;
if (values != NULL) {
    free(values);
}
```
