ldap_get_next_page function (winldap.h)

The ldap_get_next_page function returns the next page in a sequence of asynchronous paged search results.

Syntax

WINLDAPAPI ULONG LDAPAPI ldap_get_next_page(
  [in]  PLDAP       ExternalHandle,
  [in]  PLDAPSearch SearchHandle,
  [in]  ULONG       PageSize,
  [out] ULONG       *MessageNumber
);

Parameters

[in] ExternalHandle

Session handle.

[in] SearchHandle

Search block handle.

[in] PageSize

The number of entries to return in a single page.

[out] MessageNumber

The message ID for the request.

Return value

If the function succeeds, the return value is LDAP_SUCCESS.

If the function fails, it returns an error code return value. For more information, see Return Values.

Remarks

The ldap_get_next_page function is part of the interface for simple, asynchronous paging of search results. Use the search handle returned from an initial call to ldap_search_init_page and specify, in the PageSize parameter, the number of entries to be returned in a page. Set PageSize to zero to abandon a search.

Be aware that after each call to ldap_get_next_page, you must call ldap_get_paged_count for each set of results returned from the server using ldap_result. This enables the LDAP run time to save the cookie that the server passed back to maintain the search state. Other than calling ldap_get_paged_count, the results returned from ldap_get_next_page can be handled as any other search result, and must be freed when complete by calling ldap_msgfree.

When parsing the results set, be aware that it is possible for the server to return an empty page of results and yet still respond with an LDAP_SUCCESS return value. This indicates that the server was unable to retrieve a page of results, due to a timeout or other reason, but has not finished the search request. The proper behavior, in this instance, is to continue to call ldap_get_next_page until either another page of results are successfully retrieved, an error code is returned, or LDAP_NO_RESULTS_RETURNED is returned to indicate that the search is complete.

If you prefer to retrieve paged search results synchronously, use ldap_get_next_page_s.
