RE: config library, was GNOME registry

["Fox, Kevin M" <kmfox bhi010 bhi-erc com>]

I have been looking through ldap.h

It seems like a modified set of LDAP functions would work for the library
functions.

some of the ldap functions:
ldap_open();
ldap_init();
ldap_get_dn();
ldap_dn2ufn();
ldap_explode_dn();
ldap_first_attribute();
ldap_next_attribute();
ldap_get_values();
ldap_get_values_len();
ldap_count_values();
ldap_count_values_len();
ldap_init_getfilter();
ldap_getfirstfilter();
ldap_getnextfilter()
ldap_build_filter();
ldap_flush_cache();
ldap_set_cache_options();
ldap_uncache_entry();
ldap_uncache_request();
ldap_sort_entries();
ldap_sort_values();
ldap_sort_strcasecmp();
