Hi,

What does

( void ) ulCriticalNesting;

do? It is at the bottom of the portSAVE_CONTEXT macro for ARM7_LPC2000, where at the top of the macro I see

extern volatile unsigned portLONG ulCriticalNesting;


Thanks in advance,

John Alfredo

I have not checked the code, but if its where I think it is then it is just to prevent the compiler generating a warning about an unused parameter. The parameter is in fact used, but only from inline asm where the compiler does not see it.

Regards.
