37 * The main goal of this include file is to provide a platform-neutral way
38 * to define some macros that lpr wants from FreeBSD's <sys/cdefs.h>. This
39 * will simply use the standard <sys/cdefs.h> when compiled in FreeBSD, but
40 * other OS's may not have /usr/include/sys/cdefs.h (or even if that file
41 * exists, it may not define all the macros that lpr will use).
44 #if !defined(_LP_CDEFS_H_)
48 * For non-BSD platforms, you can compile lpr with -DHAVE_SYS_CDEFS_H
49 * if <sys/cdefs.h> should be included.

52 # define HAVE_SYS_CDEFS_H
54 #if defined(HAVE_SYS_CDEFS_H)
55 # include <sys/cdefs.h>
59 * __unused is a compiler-specific trick which can be used to avoid
60 * warnings about a variable which is defined but never referenced.
61 * Some lpr files use this, so define a null version if it was not
62 * defined by <sys/cdefs.h>.
64 #if !defined(__unused)
69 * All the lpr source files will want to reference __FBSDID() to
72 #if !defined(__FBSDID)
73 # if defined(lint) || defined(STRIP_FBSDID)
74 # define __FBSDID(s) struct skip_rcsid_struct
75 # elif defined(__IDSTRING) /* NetBSD */
76 # define __FBSDID(s) __IDSTRING(rcsid,s)
78 # define __FBSDID(s) static const char rcsid[] __unused = s
83 * Some lpr include files use __BEGIN_DECLS and __END_DECLS.

87 # define __BEGIN_DECLS extern "C" {
88 # define __END_DECLS }
90 # define __BEGIN_DECLS
96 * __printflike and __printf0like are a compiler-specific tricks to
97 * tell the compiler to check the format-codes in printf-like
98 * routines wrt the args that will be formatted.
