ulCriticalNestingPosted by John Alfredo on May 28, 2009 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 RE: ulCriticalNestingPosted by Richard on May 28, 2009 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.
