follow the "good examples". Each variable and function should have
a short description of the function and its parameters. The prototypes
should always contain variable names which can help to identify their
meaning; better than
int foo __P ((int, int, int, int));

Throughout the following description at various places
variables/parameters to denote sizes are required. And here the trouble
starts. In the first implementations the type of these variables was
simply @code{int}. This type was on almost all machines of this time 32
bits wide and so a de-factor standard required 32 bit variables. This
is important since references to variables of this type are passed to
the kernel.
But now the POSIX people came and unified the interface with their words
"all size values are of type @code{size_t}". But on 64 bit machines
@code{size_t} is 64 bits wide and so variable references are not anymore
possible.
A solution provides the Unix98 specification which finally introduces a
type @code{socklen_t}. This type is used in all of the cases in
previously changed to use @code{size_t}. The only requirement of this
type is that it is an unsigned type of at least 32 bits. Therefore,
implementations which require references to 32 bit variables be passed
can be as happy as implementations which right from the start of 64 bit
values.
