Why use __line__ instead of constantPosted by a_shawky on February 22, 2007 Dear All, kindly can any one clear this point to me? in COROUTINE.H header file i found this defination from coroutine.h----------------------------------------------------- #define crSET_STATE0( xHandle ) ( ( corCRCB * )xHandle)->uxState = (__LINE__ * 2); return; case (__LINE__ * 2): #define crSET_STATE1( xHandle ) ( ( corCRCB * )xHandle)->uxState = ((__LINE__ * 2)+1); return; case ((__LINE__ * 2)+1): -------------------------------------------------------------------- what is "__line__"? and why "__line__" is used instead of a constant. best regards ashawky RE: Why use __line__ instead of constantPosted by Richard on February 22, 2007 ...because each use of the macros has to have a unique number, using the line number is the easiest way of doing this. The generated numbers are used as 'cases' in a switch statement so need all be unique. As an aside - I tried replying to your email but it bounced. I have some TMS470 code I can send but it is based on an old version and I have not tested it myself. I will need a non SourceForge address if you want me to send it. Do not post email addresses in this forum however. Regards.
