See COPYRIGHT/LICENSE. .SH NAME ldap_first_entry, ldap_next_entry, ldap_count_entries \- LDAP result entry parsing and counting routines .SH LIBRARY OpenLDAP LDAP (libldap, \-lldap) .SH SYNOPSIS .nf .ft B #include <ldap.h> .LP .ft B int ldap_count_entries( LDAP *ld, LDAPMessage *result ) .LP .ft B LDAPMessage *ldap_first_entry( LDAP *ld, LDAPMessage *result ) .LP .ft B LDAPMessage *ldap_next_entry( LDAP *ld, LDAPMessage *entry ) .SH DESCRIPTION .LP These routines are used to parse results received from .BR ldap_result (3) or the synchronous LDAP search operation routines .BR ldap_search_s (3) and .BR ldap_search_st (3). .LP The .B ldap_first_entry() routine is used to retrieve the first entry in a chain of search results. It takes the \fIresult\fP as returned by a call to .BR ldap_result (3) or .BR ldap_search_s (3) or .BR ldap_search_st (3) and returns a pointer to the first entry in the result. .LP This pointer should be supplied on a subsequent call to .B ldap_next_entry() to get the next entry, the result of which should be supplied to the next call to .BR ldap_next_entry() , etc. .B ldap_next_entry() will return NULL when there are no more entries. The entries returned from these calls are used in calls to the routines described in .BR ldap_get_dn (3), .BR ldap_first_attribute (3), .BR ldap_get_values (3), etc. .LP A count of the number of entries in the search result can be obtained by calling .BR ldap_count_entries() . .SH ERRORS If an error occurs in .B ldap_first_entry() or .BR ldap_next_entry() , NULL is returned and the ld_errno field in the \fIld\fP parameter is set to indicate the error. If an error occurs in .BR ldap_count_entries() , -1 is returned, and .B ld_errno is set appropriately. See .BR ldap_error (3) for a description of possible error codes. .SH SEE ALSO .BR ldap (3), .BR ldap_result (3), .BR ldap_search (3), .BR ldap_first_attribute (3), .BR ldap_get_values (3), .BR ldap_get_dn (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 81 stdin
