Problem with .api Configuration

#1

Hey, i wrote a function getConfig that reads a file “config.conf” in one App.
Now i want to call that Function in another App using a .api file. I guess somethings wrong with my API file but i am not sure what. But after specifying the api file and compiling i get following error:

/home/reinhard/myLeafWorkspace/CL_Agents/Components/CL_ConfigComponent/CL_Config.c:26:6: error: conflicting types for ‘IF_Config_getConfig’
void IF_Config_getConfig(char* customerId,char* siteId, char* locationId, char* host, int* port, int* enableTls);

(Without the API file it compiles fine)

My API file looks like this:

FUNCTION int32 getConfig
(
string customerId[7] OUT,
string siteId[5] OUT,
string locationId[2] OUT,
string host[30] OUT,
int32 port OUT,
int32 enableTls OUT
);

Thanks in advance!

you can delete one by one to know which one makes the problem:

string customerId[7] OUT,
string siteId[5] OUT,
string locationId[2] OUT,
string host[30] OUT,
int32 port OUT,
int32 enableTls OUT

It seems to be all of them, when i change OUT to IN and change char* to const char* i stop getting that error but of course i don’t want to send the DAta in i want to get the data out.

The function is declared like:
int IF_Config_getConfig(char* customerId,char* siteId, char* locationId, char* host, int* port, int* enableTls);

From your previous discussion thread, the IPC_step4.rar already use both OUT and IN, but you say it is ok.

And here says string must be IN:

Oh, that’s because I changed it up for my needs and i only needed IN.

Where does it say that? Under “Specifying a Function” a OUT string is listed as an example.

I now tried passing the Data as struct and i get following error:

API:

STRUCT SWI_Config
{
string customerId[7];
string siteId[5];
string locationId[2];
string host[30];
int32 port;
int32 enableTls;
};

FUNCTION SWI_Config getConfig
(
);

Function:
IF_Config_SWI_Config_t IF_Config_getConfig();

Got it to work using struct.
Still thanks!

I found that you need to add one more parameter(message2Size) in the .c file in case you need to add OUT string:

void logger_logMessage
(
	const char* message ,     ///< [IN]
char* message2,
       
    size_t message2Size
)
{
	LE_INFO( PREFIX_LOG_MSG "received the message \"%s\" from a client.",
		     message );


	snprintf( message2, MESSAGE_SIZE,
		          "1234123412341324");
		message2[ MESSAGE_MAX ] = '\0';


}



FUNCTION logMessage
(
	string	message[MSG_API_SIZE] IN,
	string	message2[MSG_API_SIZE] OUT
);

Thanks that will be very useful!
