On Windows platforms (excluding Cygwin), error codes for
|
|
@code{getsockopt} are not placed in @code{errno}, and
|
|
@code{WSAGetLastError} must be used instead.

Portability problems not fixed by Gnulib:

This function is missing on some platforms:
|
|
BeOS.
|
|
@item
|
|
Some platforms don't have a @code{socklen_t} type; in this case this function's
|
|
fifth argument type is @samp{int *}.
|
|
@item
|
|
Many socket options are not available on all platforms.
|
|
@item
|
|
BeOS has the @code{setsockopt} function, but not the @code{getsockopt}
|
|
function.
