That's the one I meant.

"man types" in SunOS 3.2 lists the types and explains some of them, but
not size_t.  Since one of the differences between BSD and SysV is that
read() and write() take "unsigned" length parameters in SysV but "int"
ones in BSD, while size_t is "unsigned int" in V.3's <sys/types.h> but
"int" in 4.2's <sys/types.h>, I assumed that it was the size_t of the
dpANS.  I'm sorry to hear that this was just good luck.  What *is*
the size_t in <sys/types.h> for, then?
