pre-processor __LINE__ not working ?

[nurquhar]

I have been trying to use __LINE__ to report the current line to help with my debugging.

However PCM 3.249 gives the error :
Line 1375(16,17): Expecting LVALUE such as a variable name or * expression ::

for the following line of code :
printf(__LINE__) ;

if I replace with
printf(__FILE__) ;

its ok ?

Indeed the example given in help file don't work either, CCS says it too long ie :
printf("Too many entries, source file: " __FILE__ " at line " __LINE__ "\r\n");



Whats going on ?

Would you believe it, the CCS PCM Documatation is wrong !

__LINE__ is not type char* but long.

Thus to print your line number you actually need to use something like this :

printf("Line : %ld\r\n", __LINE__) ;

And not as implied in the manual :

printf("Line : " __LINE__ "\r\n") ;
