These routines are used to parse results received from ldap_result(3)
or the synchronous LDAP search operation routines ldap_search_s(3)
The ldap_first_entry() routine is used to retrieve the first entry in
a chain of search results. It takes the result as returned by a call
to ldap_result(3) or ldap_search_s(3) or ldap_search_st(3) and
returns a pointer to the first entry in the result.
This pointer should be supplied on a subsequent call to
ldap_next_entry() to get the next entry, the result of which should
be supplied to the next call to ldap_next_entry(), etc.
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 ldap_get_dn(3), ldap_first_attribute(3),
A count of the number of entries in the search result can be obtained
by calling ldap_count_entries().
If an error occurs in ldap_first_entry() or ldap_next_entry(), NULL
is returned and the ld_errno field in the ld parameter is set to
indicate the error. If an error occurs in ldap_count_entries(), -1
is returned, and ld_errno is set appropriately. See ldap_error(3)
for a description of possible error codes.
