[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [May 2009 Threads] 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.
