Defect Report:

Chapter 8 of POSIX.1 lists the functions required from the C
Standard, required as part of POSIX.1 with the C Language
Binding.  Section 8.1 lines 25-29 specify the particular
input/output functions required.  Section 8.2 lines 193-198
state that functions from the C standard which "creat[e] a
file shall do so as if they called the creat() function"
with specified flags.  Section 8.2.3 lines 341-345 describe
that each function operating on a stream has "underlying
functions" which "share certain traits with the underlying
functions, but [do] not require that there be any relation
between the implementations of the stream function and its
underlying functions."

In lines 341-345, what does the term "share certain
traits" mean?  The descriptions of the individual
functions list attributes in common with the underlying
functions...is that what is intended?

WG15 response for ISO/IEC 9945-1:1990 (IEEE Std 1003.1-1990)

The "underlying functions" are referenced only
with regard to error detection ( The phrase "share
certain traits" imposes no additional normative requirements
on its own.
