# fsCameraEnumerateCameraDefinitions<no value>
The `fsCameraEnumerateCameraDefinitions` function is used to retrieve an array of all the defined camera names.

 

##### Syntax

bool fsCameraEnumerateCameraDefinitions(
    char** outArrCameraDefinition,
    int* outArrSize
    );
```

|--------------------------|----------------------------------------------------------------------------|
| `outArrCameraDefinition` | Pointer to an array of strings storing the names of the Camera Definitions |
| `outArrSize`             | Pointer to an int representing the size of the array.                      |

##### Return Values

The function returns `false` if it was not possible to send the request, otherwise it will return `true`. If the request was sent but failed, the specified callback will be invoked with an appropriate error code.

 

##### Remarks

The function *allocates* and *fills* an array of strings (`char*`) with a size of 256 char each. It is the responsibility of the client to free the memory allocated. The function also fills the `outArrSize` parameter with the size of the array, however the memory for this parameter *must be allocated by the client*. See the example sample below:

``` wasm
char* listCamDef  = nullptr;          // Null pointer
int   camDefCount = 0;                // Allocated int
 
if (!fsCameraEnumerateCameraDefinitions(&listCamDef, &camDefCount))
{
    std::cout << "Error with allocation";
    return;
}
 
char* tmpPtr = listCamDef;
for (int i = 0; i < camDefCount; ++i) // Iterate throught the array
{
    std::cout << tmpPtr;
    tmpPtr += 256;                    // Go to the next string (256 char each)
}
 
free(listCamDef);                     // free the memory when it's no longer used
```
