Portability problems fixed by Gnulib:

This function is missing on some platforms:
|
|
OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11.23, Solaris 9, mingw, MSVC 14.

@item
|
|
On some platforms, this function fails to detect invalid fds with
|
|
EBADF, but only if they lie beyond the current maximum open fd:
|
|
FreeBSD 8.2.

Portability problems not fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
This function has a slightly incompatible declaration on some platforms:
|
|
AIX 7.1 (when @code{_ALL_SOURCE} is defined).
|
|
@item
|
|
When the @var{sigmask} argument is nonnull on platforms that do not
|
|
natively support this function, race conditions are possible when its
|
|
gnulib implementation temporarily modifies the signal mask, and the
|
|
behavior is unspecified in a multi-threaded process.
