Here is a macro I employ to use temporary stack storage
for these sort of situations & longword align it..
Note: allocation MUST be at least 4 bytes bigger than you need.
because alignment rounds up to next longword.
#define LALIGN(x) ((x+3L)&0xFFFFFFFCL)
AUTO UBYTE fbuffer[ sizeof(struct FileInfoBlock) + 4L ];
STRUCT FileInfoBlock *fib;
fib = LALIGN ( fbuffer );
Examine(lock, fib);
