define for printf

[juhlin]

Hi

Does someone know who to do a #define with unknown number of parameters, for printf ? Here is what I want to do (in valid GCC syntax)

#define lprintf(text...) printf(lcd_putc, text)

And now it's possible todo the following :

lprintf("hello world");
lprintf("number of i is %d", d);
lprintf("file %s on line %d", __FILE__, __LINE__);

Unfortanly CCS complain about me define. Is it possible to use any other syntax to get what I want?

In the distant past, I used this form using doubled parentheses. I haven't tried it on CCS, but it has worked on other compilers.

NB: You can make an ugly mess of your code doing this. At least *I* have.
