Indirection to different types

calou — Wed, 17 Jan 2007 23:26:12 GMT

Hello,

I have this definition :

SBYTE const SUIVANT[6]={'S','U','I','V',1,0};

I call the function LCDPutString(SUIVANT,2,15) which is defined like it :

void LCDPutString(SBYTE *s,BYTE lgn,BYTE pos)

When i compile i have this warning : Indirection to different types ('const signed char *' instead of 'signed char *')

I undestand this warning but would it be possible to do something to avoid it? I could declare SUIVANT not in const but i will lose ram. The LCDPutString can receive other arguments that const arguments.

How can i do?

Thank you very much

Regards

Does LCDPutString ever change its first argument? Given the name of the function I would not expect this.
If it does never change the s parameter, you can add the const there as its not a problem to call "const SBYTE *"'s with a "SBYTE *", only the other way around does cause the warning.

Thank you for your answer. The content of s is not changed
