A (very!) small optimization in tasks.c

Posted by Marcel van Lieshout on February 3, 2005
Just a minor thing...

In prvInitialiseTCBVariables() the taskname is copied to the tcb after verifying it's length. When it fits a strcpy is used, otherwise a strncpy.

I think it simplifies the code (and save some cycles, too) when the test is removed and the strncpy is always used.

Good point! I've added it to the list.

It would be neat, I think, if a \0 was always put in the last char of the taskname. Then, when a taskname is too long to fit, it still is a properly terminated string.

The strncpy should copy "maxlen - 1" chars.
