Thread: returning two structure value from a single fucntion

I am not clear as to what you are trying to do. Are you trying to modify con_get_dev_con_status_sync so as to get both with a single call to con_get_dev_con_status_sync? If so, the solution is simple: change con_get_dev_con_status_sync to have two parameters.

I have one function :

Code:

void con_get_dev_con_status_sync(ST_DEV_CONNECTION_STATUS_NOTIFY *dev_info)
{ 
    printf("HF PMASK :: %d\n",SyncData.dev_info1.profile_mask);
    printf("AUD PMASK :: %d\n",SyncData.dev_info2.profile_mask);
    if(SyncData.dev_info1.profile_mask == 0x01)
    {
        printf("Dev1 SYNC INFO\n");
        dev_info>connection_status=SyncData.dev_info1.connection_status;
        dev_info->devHandle=SyncData.dev_info.devHandle;
        dev_info->devNameInfo=SyncData.dev_info.devNameInfo;
    }
    else if(SyncData.aud_dev_info.profile_mask == 0x06)
    { 
        printf("Dev2 SYNC INFO\n");
        dev_info>connection_status=SyncData.dev_info2.connection_status;
        dev_info->devHandle=SyncData.dev_info2.devHandle;
        dev_info->NameInfo=SyncData.dev_info.devNameInfo;
    }
}

In above implentation, dev_info struct will be over written when
SyncData.dev_info1.profile_mask = 0x01 and
SyncData.dev_info2.profile_mask = 0x06

Looks like you have not placed the complete code here.

You have passed (ST_DEV_CONNECTION_STATUS_NOTIFY *dev_info) to the function but you are accessing some values from struct SyncData (must be a global structure or at least a static struct which can be accessible from the same file).

The SyncData has SyncData.dev_info1 and SyncData.dev_info2.

If I am not wrong then you are thinking to pass both the SyncData.dev_info1 and SyncData.dev_info2 structure pointers to the function instead of accessing them from the global struct SyncData.

You can do it by taking an array of pointers to structures of type ST_DEV_CONNECTION_STATUS_NOTIFY.

Have a look on the below declaration:
ST_DEV_CONNECTION_STATUS_NOTIFY *dev_info_array[2];

dev_info_array[0] = SyncData.dev_info1;
dev_info_array[1] = SyncData.dev_info2;

Now call the function with:
con_get_dev_con_status_sync(dev_info_array);

and inside the function definition access the dev_info1 from index 0 and dev_info2 from index 1 off dev_info_array.

If this is not you want then place the complete code if possible and clarify what you want.
