Thanks a lot in advance. Tip: Also try mail lists & web of the UPS ports on FreeBSD (4 when I counted, a couple of year back,) inc. my favourite: /usr/ports/sysutils/nut -- This is a developing project to monitor a large assortment of UPS hardware.

Re: Invalid realloc size of 0 when installing on an AMD athlonXP barton poweredmachine
Turned out to be a bug in sysinstall when booting from a floppy and installing over a network, I had no problems when I just wrote the ISO but I prefer network install since it takes me about an hour to download the ISO, and by that time I could have the machine up and running if I used network install.

C code for parsing rc.conf?
Hi, Is there a C library that comes with FreeBSD which can be used to parse, append to, and validate rc.conf? I'd like to customize some of the settings in /etc/rc.conf with my own GUI-based program. It's not too hard to write something on my own, but I was wondering if a reusable library existed in FreeBSD 4.x or 5.x for doing this. Thanks. -- Craig Rodrigues http://crodrigues.org [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

So make sure your gui tool preserves unchanged lines when saving (instead of regenerating the entire file from a parsed array, for example). That will let an admin use shell tricks to generate ifconfig_XX0_aliasXX variables, for example, and still allow using your tool to change moused flags. -- Dan Nelson [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Re: C code for parsing rc.conf?
Not that I know of, but it should be a breeze to write a simple parsing engine.
Just ignore all lines starting with a '#', and break at the '=' sign. The
first part would be your variable name, the last part your value for it.
Then just display variables and their names, and maybe parse the variable
names so you can assign meaningful help information to them.
I didn't compile this, not sure if it'll work, but it'll give you a good
idea as to what your code may look like ..
int main(int argc, char **argv)
{
FILE *rc;
char buf[512];
if ( (rc=fopen("/etc/rc.conf", "r")) == NULL)
{
perror("fopen()");
exit(EXIT_FAILURE);
}
while (fgets(buf, sizeof(buf), rc) != NULL)
{
char *eq_ptr, var_name[256], var_value[256];
some_function_to_strip_trailing_and_pre_whitespace(buf);
/* this function will just strip pre- and trailing whitespace from the line */
if (!strlen(buf)) continue;/* blank line */
if (buf[0] == '#') continue; /* comment line */
if ( (eq_ptr = index(buf, '=')) == NULL) continue; /* no equal
sign */
*eq_ptr = '\0';
memset(var_name, 0, 256);
memset(var_value, 0, 256);
if (!strlen(buf) || !strlen(eq_ptr+1)) continue;/* either
the variable name or the value was empty */
strncpy(var_name, buf, 255);
strncpy(var_value, eq_ptr+1, 255);
printf("%s=%s\n", var_name, var_value);
}
exit(EXIT_SUCCESS);
}

Ah yes, I was just being crude .. giving some lame example :-P Parsing the rc.conf would take considerably more work than that "Tha whistles go WOO!" - Bubb Rubb Brandon At 04:59 PM 4/14/2004, you wrote: --- Brandon Erhart <[EMAIL PROTECTED]> wrote: > Not that I know of, but it should be a breeze to write a simple parsing > engine. > Just ignore all lines starting with a '#', and break at the '=' sign.

It's not too hard to write something on my own, but I was wondering if a reusable library existed in FreeBSD 4.x or 5.x for doing this. There was a detailed discussion of this topic about a year ago. Here is how to obtain the current settings from rc.conf from within a C program: * Clear the current environment * popen() a shell command that sources rc.conf, then runs printenv * read and parse the output of printenv The basic idea is to just let the shell do the work for you. You can make this process a bit more predictable by using a modified printenv that dumps variable names and values in hex or something similar. (Or, submit a patch to the existing printenv.) To update rc.conf, just append new statements to the end of the file. Don't try to edit it in place. Later variable settings will override earlier ones, so this will have the expected result without possibly trashing someone's custom shell scripting. I may have overlooked a few details, but this should be enough to get you started.

It's a little more awkward, but another way to do this is to use a shell shim along the lines of #!/bin/sh . /etc/whatever exec /your/program The shell's environment will be exported to your program's environment.
