* use _DIAGASSERT() to check pointer arguments against NULL and file descriptors against -1 (as appropriate). * add actual checks which to detect stuff that would trigger_DIAGASSERT(), and attempt to return a sane error condition. * knf some code * remove some `register' decls.
the first two items result in the addition of code similar to the following in various functions:
_DIAGASSERT(path != NULL) #ifdef _DIAGNOSTIC if (path == NULL) { errno = EFAULT; return (-1); } #endif
