The header
.I <libsimple.h>
defines the following symbols if at least one them are defined:
.BR AF_LOCAL ,
.BR AF_UNIX ,
and
.BR AF_FILE ;
the following symbols if at least one them are defined:
.B AF_NETLINK
and
.BR AF_ROUTE ;
the following symbols if at least one them are defined, or if their
.B AF_
counterpart is defined:
.BR PF_LOCAL ,
.BR PF_UNIX ,
and
.BR PF_FILE ;
the following symbols if at least one them are defined, or if their
.B AF_
counterpart is defined:
.B PF_NETLINK
and
.BR PF_ROUTE .
Additionally, unless
.B DONT_DEFINE_CLOCK_MONOTONIC_RAW
is defined,
.B CLOCK_MONOTONIC_RAW
is defined to
.BR CLOCK_MONOTONIC ,
unless the system defines
.BR CLOCK_MONOTONIC_RAW .
.PP
The header
.I <libsimple.h>
also defines, without a value,
.B TWOS_COMPLEMENT
if two's complement is used to represent signed integers,
.B ONES_COMPLEMENT
if ones' complement is used to represent signed integers, or
.B SIGN_MAGNITUDE
if sign\-magnitude is used to represent signed integers. Since
no other representation is permitted in C, the header
.I <libsimple.h>
will define exactly one of these macros.
.PP
The header
.I <libsimple.h>
