Check if key is found in IniFileLib

Dear experts

I am using the IniFileLib (https://os.mbed.com/users/rinosh2/code/IniFileLib/) library to read my .ini file.

How do I know if a key is found or not in an if statement?

Kind regards

Hi Jordy,

You can use this API IniFile::Status IniFile::get(const char* key, char* ret, int ret_size() to get the key, and check the error code returned.

// error code
    typedef enum {
        S_SUCCESS,
        S_OPEN_ERROR,
        S_NOT_OPENED,
        S_NO_KEY,
        S_BUFFER_TOO_SHORT,
        S_FORMAT_ERROR,
    } Status;

Regards, Desmond

Hi, thanks for your reply!

I tried to do this, but it didn't work for me.

I tried this:

code

int number;
if(IniFile::getval("/local/file.ini", "Number", number) == IniFile::Status::S_NO_KEY)
{…}

What did I do wrong?

Kind regards

What do you mean it didn't work for you? Compilation failure or run time failure? Do you have any logs?

Thanks, Desmond
