Code is in C.
The code is very huge..

But here is a very small portion of code to read the file..

if ((cnf = fopen(zl->MlConfFile, "r")) == NULL) {
zl->warn(zl, LOG_ERR, "Failed to open multilevel library config file '%s'",
zl->MlConfFile);
return -1;
}

while(!feof(cnf)) {
/* Scan first line, hopefully containing the name of a node */
if (fgets(buf, MAXSTRBUF, cnf) == NULL) {
if (!feof(cnf)) /* Get rid of warning when EOD */
zl->warn(zl, LOG_ERR,
"Failed to read from multilevel config file '%s' %s",
zl->MlConfFile, strerror(errno));
break;
}
i++;
