The +.BR ldap_msgtype (3) +function can be used to distinguish between the different message types. +.LP +The +.B ldap_first_message() +routine is used to retrieve the first message in a result chain. +It takes the \fIresult\fP as returned by a call to +.BR ldap_result (3) , +.BR ldap_search_s (3) +or +.BR ldap_search_st (3) +and returns a pointer to the first message in the result chain. +.LP +This pointer should be supplied on a subsequent call to +.B ldap_next_message() +to get the next message, the result of which should be +supplied to the next call to +.BR ldap_next_message() , +etc. +.B ldap_next_message() +will return NULL when there are no more messages. +.LP +These functions are useful when using routines like +.BR ldap_parse_result (3) +that only operate on the first result in the chain. +.LP +A count of the number of messages in the result chain can be obtained +by calling +.BR ldap_count_messages() . +It can also be used to count the number of remaining messages in a chain +if called with a message, entry or reference returned by +.B ldap_first_message() , +.B ldap_next_message() , +.BR ldap_first_entry (3) , +.BR ldap_next_entry (3) , +.BR ldap_first_reference (3) , +.BR ldap_next_reference (3) . +.SH ERRORS +If an error occurs in +.B ldap_first_message() +or +.BR ldap_next_message() , +NULL is returned. If an error occurs in +.BR ldap_count_messages() , +-1 is returned. +.SH SEE ALSO +.BR ldap (3), +.BR ldap_search (3), +.BR ldap_result (3), +.BR ldap_parse_result (3), +.BR ldap_first_entry (3), +.BR ldap_first_reference (3) +.SH ACKNOWLEDGEMENTS +.so ../Project |
