.SH DESCRIPTION
.sp
.LP
\fBldap_count_messages()\fR is used to count the number of messages that remain
in a chain of results if called with a  message, entry, or reference returned
by  \fBldap_first_message()\fR, \fBldap_next_message()\fR,
\fBldap_first_entry()\fR, \fBldap_next_entry()\fR,
\fBldap_first_reference()\fR, and  \fBldap_next_reference()\fR
.sp
.LP
\fBldap_first_message()\fR and   \fBldap_next_message()\fR functions are used
to step through the list of messages in a result chain returned by
\fBldap_result()\fR.
.sp
.LP
\fBldap_msgtype()\fR function returns the type of an LDAP message.
.SH RETURN VALUES
