AFAIKS, there IS getgrent implemented via getgrent_r(). Nevertheless,
assume we wanna avoid it. Try
parser_t *parser = config_open2(filename, fopen_or_warn);
if (parser && pwd) {
char *group_name;
while (config_read(parser, &group_name, 1, 1, "#:", PARSE_NORMAL)) {
// use group_name as needed
// ...
}
config_close(parser);
}
llist_t* seems saner, but I'd suggest to develop both versions for now.
BTW, why do we use getgrnam() if the names of the aux groups are
available directly when we read a line from /etc/group?!
