+POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/select.html}
+
+Gnulib module: select
+
+Portability problems fixed by Gnulib:
+@itemize
+@item
+On Windows platforms (excluding Cygwin), @code{select} can only be
+called on descriptors created by the @code{socket} function, not on regular
+file descriptors.
+@item
+On Windows platforms (excluding Cygwin), error codes for @code{accept} are not
+placed in @code{errno}, and @code{WSAGetLastError} must be used instead.
+@item
+This function fails when the @code{nfds} argument is 0 on some platforms:
+Interix 3.5.

+Portability problems not fixed by Gnulib:
+@itemize
+@item
+When you call @code{select} with a timeout, some implementations modify the
+timeout parameter so that upon return from the function, it contains the
+amount of time not slept.  Other implementations leave the timeout parameter
+unmodified.
+@item
+On BeOS, @code{select} can only be called on descriptors created by the
+@code{socket} function, not on regular file descriptors.
+@item
+On Solaris 2.6 and older, @code{select} applied to a file descriptor opened
+for reading and associated with @code{/dev/null} hangs, waiting for input,
+when instead it should return immediately.
+@item
+On Linux, when some file descriptor refers to a regular file, @code{select}
+may fail, setting @code{errno} to @code{EBADF}.
+@item
+This function is declared in @code{<unistd.h>}, not @code{<sys/select.h>},
+on some platforms:
+IRIX 5.3.
