See COPYRIGHT/LICENSE. .SH NAME ldap_first_reference, ldap_next_reference, ldap_count_references \- Stepping through continuation references in a result chain .SH LIBRARY OpenLDAP LDAP (libldap, \-lldap) .SH SYNOPSIS .nf .ft B #include <ldap.h> .LP .ft B int ldap_count_references( LDAP *ld, LDAPMessage *result ) .LP .ft B LDAPMessage *ldap_first_reference( LDAP *ld, LDAPMessage *result ) .LP .ft B LDAPMessage *ldap_next_reference( LDAP *ld, LDAPMessage *reference ) .SH DESCRIPTION .LP These routines are used to step through the continuation references in a result chain received from .BR ldap_result (3) or the synchronous LDAP search operation routines. .LP The .B ldap_first_reference() routine is used to retrieve the first reference 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 reference message in the result chain. .LP This pointer should be supplied on a subsequent call to .B ldap_next_reference() to get the next reference message, the result of which should be supplied to the next call to .BR ldap_next_reference() , etc. .B ldap_next_reference() will return NULL when there are no more reference messages. The reference messages returned from these calls are used by .BR ldap_parse_reference (3) to extract referrals and controls. .LP A count of the number of reference messages in the search result can be obtained by calling .BR ldap_count_references() . It can also be used to count the number of reference messages remaining in a result chain. .SH ERRORS If an error occurs in .B ldap_first_reference() or .BR ldap_next_reference() , NULL is returned. If an error occurs in .BR ldap_count_references() , -1 is returned. .SH SEE ALSO .BR ldap (3), .BR ldap_result (3), .BR ldap_search (3), .BR ldap_parse_reference (3) .SH ACKNOWLEDGEMENTS .lf 1 ./../Project .\" Shared Project Acknowledgement Text .B "OpenLDAP Software" is developed and maintained by The OpenLDAP Project <http://www.openldap.org/>. .B "OpenLDAP Software" is derived from the University of Michigan LDAP 3.3 Release. .lf 72 stdin
