NAME

7       try parsing and counting routines

LIBRARY

SYNOPSIS

13       #include <ldap.h>
14
15       int ldap_count_entries( LDAP *ld, LDAPMessage *result )
16
17       LDAPMessage *ldap_first_entry( LDAP *ld, LDAPMessage *result )
18
19       LDAPMessage *ldap_next_entry( LDAP *ld, LDAPMessage *entry )
20

DESCRIPTION

22       These routines are used to parse results received  from  ldap_result(3)
23       or  the synchronous LDAP search operation routines ldap_search_s(3) and
24       ldap_search_st(3).
25
26       The ldap_first_entry() routine is used to retrieve the first entry in a
27       chain  of search results.  It takes the result as returned by a call to
28       ldap_result(3) or ldap_search_s(3) or ldap_search_st(3) and  returns  a
29       pointer to the first entry in the result.
30
31       This  pointer  should be supplied on a subsequent call to ldap_next_en‐
32       try() to get the next entry, the result of which should be supplied  to
33       the next call to ldap_next_entry(), etc.  ldap_next_entry() will return
34       NULL when there are no more entries.  The entries returned  from  these
35       calls  are  used  in calls to the routines described in ldap_get_dn(3),
36       ldap_first_attribute(3), ldap_get_values(3), etc.
37
38       A count of the number of entries in the search result can  be  obtained
39       by calling ldap_count_entries().

ERRORS

42       If  an error occurs in ldap_first_entry() or ldap_next_entry(), NULL is
43       returned and the ld_errno field in the ld parameter is set to  indicate
44       the error.  If an error occurs in ldap_count_entries(), -1 is returned,
45       and ld_errno is set appropriately.  See ldap_error(3) for a description
46       of possible error codes.
