|4.2.4. C library differences|
Editing the parameters in this section will require you to look around at the files in your /usr/include directory. The SIZE_T parameter is the datatype of the ``size'' parameters in subroutine calls like memchr and fread. The LOCK_STYLE parameter specifies how file-locking should be done. Innxmit is the only program that locks files; if you use the provided scripts, this isn't even necessary, so you can set this to ``NONE'' if you have any compile problems. The DIR_STYLE parameter specifies what is returned by your readdir(3) routine. This will be either a ``struct direct'' or a ``struct dirent''; set the parameter to ``DIRECT'' or ``DIRENT'' as appropriate. If you do not have Unix-domain sockets, set HAVE_UNIX_DOMAIN to ``DONT.'' This means that INN will use a named pipe for the communication between innd and ctlinnd. It also means that there will be no local ``private'' port for rnews to use; this should not cause any problems, although it makes it easier for anyone to use rnews and post fake news articles. (You might also have to modify the syslog routines; see the end of the file syslog/README for details on this.) INN needs to know how many descriptors are available to use for files and sockets. There are several ways to get this number; the FDCOUNT_STYLE parameter specifies which method to use. On most systems, the getdtablesize routine will do this, so leave the default of ``GETDTAB.'' On other systems you need to use the getrlimit, sysconf or ulimit routine, so set the parameter to ``GETRLIMIT'', ``SYSCONF'', or ``ULIMIT'', respectively. If you do not have any of those calls then set the parameter to ``CONSTANT'' and edit the file lib/getdtab.c to return the right number. To get this number, look for an OPEN_MAX constant in your system header files, or write a program that repeatedly opens /dev/null until it gets an error. The last few parameters in this section, xxxVAL, are used primarily to keep lint quiet. These functions are declared in include/clibrary.h, and the return values are pretty much always ignored. You can usually determine what these values should be by examining your manpages or your lint libraries.
