Warnings when getting strings from the Device Layer

Question

HI,

When I get a string from the Device Layer, I get the following errors:

../GeneratedCode/Application.c:144:18: warning: implicit declaration of function ‘DeviceDriver_GetRecipeName’ [-Wimplicit-function-declaration]
     recipeName = DeviceDriver_GetRecipeName();
                  ^~~~~~~~~~~~~~~~~~~~~~~~~~
../GeneratedCode/Application.c:144:16: warning: assignment to ‘XString’ {aka ‘short unsigned int *’} from ‘int’ makes pointer from integer without a cast [-Wint-conversion]
     recipeName = DeviceDriver_GetRecipeName();
 

How do I declare DeviceDriver_GetRecipeName as it is a native call and how do I fix the XString warning?

Thanks

Phil

Hi Phil,

in order to provide the declaration of your native functions let me recommend to add an Inline Code into your device class - there you can add your #include statement. Please don't forget to adjust the order of the Inline Code member so that the #include statement will be arranged at the beginning of the C file. 

Concerning the string warning, let me recommend the chapter Be careful when exchanging strings - it describes all aspects when transferring strings from and to a device driver.

Hope this helps...

Best regards,

Manfred.

Thanks Manfred, it was the position of the Inline code that was the issue, moving it to 'Bottom' solved both issues.
