Portability problems fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
This function is declared in @code{<winsock2.h>}
|
|
instead of @code{<sys/socket.h>}
|
|
on some platforms:
|
|
mingw, MSVC 14.
|
|
@item
|
|
On Windows platforms (excluding Cygwin), error codes from this function
|
|
are not placed in @code{errno}, and @code{WSAGetLastError} must be used
|
|
instead.
|
|
@item
|
|
On HP-UX 11, in 64-bit mode, when the macro @code{_HPUX_ALT_XOPEN_SOCKET_API}
|
|
is not defined, this function behaves incorrectly because it is declared
|
|
to take a pointer to a 64-bit wide @code{socklen_t} entity but in fact
|
|
considers it as a pointer to a 32-bit wide @code{unsigned int} entity.

Portability problems not fixed by Gnulib:

@itemize

@item
|
|
Some platforms don't have a @code{socklen_t} type; in this case this function's
|
|
fifth argument type is @samp{int *}.
|
|
@item
|
|
On some platforms, this function's fifth argument type is @samp{void *},
|
|
not @samp{socklen_t *}:
|
|
Solaris 11 OmniOS.
|
|
@item
|
|
Many socket options are not available on all platforms.
