In the AutoDocs (available from C/A for $20 as part of the Native Developers
Upgrade Disk from CATS,  1200 Wilson Dr, West Chester, PA) there is some
fairly complete documentation on the C type functions that are available
in Amiga.Lib. Be forewarned however that they do not use a compatible 
stdio pointer (FILE *) that Lattice uses. So to use these functions with
Lattice, the following steps must be taken :
    o Link with TWStartup.o rather than c.o. This opens stdin and stdout
	with C/A style file handles rather than Lattice file handles.
    o Link first with *just* Amiga.lib and make sure that you haven't
	used any of Lattice's routines that depend on stdin or stdout.
    o Then link with Amiga.lib first, and LC.lib second. 

When using these routines note that they expect 16 bit ints for such things
as the %d format so if you print a Lattice int use %ld as the format specifier.
Also C/A's printf does not support floating point formats that I know of.

These opinions are my own and no one elses, but you knew that didn't you.
