Okay, this is a bit old, but I found it, and it was fun to do ;)) <BR>
SUN needed the configuration of our system, I could do it in C<BR>
but didn't feel like cutting and pasting everything:<BR>
<CODE>
#!/usr/bin/perl -w
use strict;

my (@Variables,@Code);

foreach (`man sysconf`)
{
 s/^\s+//;
 my $Var=(split /\s+/,$_,2)[0] or next;
 next unless ($Var=~/^_[A-Z_]+$/o);
 my $Cvar=lc $Var;
 push @Variables,"long int $Cvar=sysconf($Var);";
 push @Code,"printf(\"$Var set to: \%d\\n\",$Cvar);";
};
local $"="\n ";

print << "PROGRAM";
#include <stdio.h>
#include <unistd.h>

int main (argc,argv)
int argc;
char *argv[];
{
 @Variables
 @Code
}
PROGRAM
</CODE>
<BR>
Presto!!! redirect to getconf.c, compile, run, be happy....<BR>
<BR>
I have to add here that this code is NOT <BR>
very portable... In this case it didn't need to be... <BR>
It was short and worked ([jeroenes] posted an update here, and<BR>
I did some updating myself, so this should have made it a bit<BR>
more portable (for what I don't know though ;))<BR>
<BR>
You MAY run into gcc compiling errors, this is a result from labels in<BR>
the man page not being in your include file<BR>
delete those items ;))<BR>
