7 Gnulib module: stdio, nonblocking
9 Portability problems fixed by Gnulib module @code{stdio}, together with module @code{nonblocking}:
12 When reading from a non-blocking pipe whose buffer is empty, this function
13 fails with @code{errno} being set to @code{EINVAL} instead of @code{EAGAIN} on
18 Portability problems not fixed by Gnulib:
21 C99 and POSIX.1-2001 and later require end-of-file to be sticky, that
22 is, they require this function to act as if it reads end-of-file if
23 @code{feof} would return nonzero. However, on some systems this
24 function attempts to read from the underlying file descriptor even if
25 the stream's end-of-file indicator is set. These systems include
26 glibc and default Solaris.
28 On Windows platforms (excluding Cygwin), this function does not set @code{errno}
31 This function crashes if the stream's file descriptor has already been
32 closed, if @code{MSVC_INVALID_PARAMETER_HANDLING} is
33 @code{HAIRY_LIBRARY_HANDLING} or @code{SANE_LIBRARY_HANDLING},
