1/6/2010
This function searches the LDAP directory and returns a requested set of attributes for each entry matched.
Syntax
ULONG ldap_search_ext_s(
LDAP* ld,
UNICODE PTCHAR base,
ULONG scope,
UNICODE PTCHAR filter,
UNICODE PTCHAR attrs[],
ULONG attrsonly,
LDAPControl** ServerControls,
LDAPControl** ClientControls,
struct l_timeval* timeout,
ULONG SizeLimit,
LDAPMessage** res
);
Parameters
- ld
[in] Session handle.
- base
[in] Distinguished name of the entry at which to start the search.
scope
[in] Specifies one of the following values to indicate the scope of the search.Value Description LDAP_SCOPE_BASE
Searches the base entry only.
LDAP_SCOPE_ONELEVEL
Searches all entries in the first level below the base entry, excluding the base entry.
LDAP_SCOPE_SUBTREE
Searches the base entry and all entries in the tree below the base.
- filter
[in] Pointer to a null-terminated string that specifies the search filter.
- attrs
[in] Null-terminated array of strings indicating which attributes to return for each matching entry. Pass NULL to retrieve all available attributes.
- attrsonly
[in] Boolean value that should be zero if both attribute types and values are to be returned and nonzero if only types are wanted.
- ServerControls
[in] List of LDAP server controls.
- ClientControls
[in] List of client controls.
- timeout
[in] Specifies both the local search time-out value in seconds and the operation time limit that is sent to the server within the search request.
- SizeLimit
[in] Limit on the number of entries to return from the search. A value of zero means no limit.
- res
[out] Contains the results of the search upon completion of the call.
Return Value
If this function succeeds, the return value is LDAP_SUCCESS.
If this function fails, it returns an error code. See the LDAP_RETCODE enumeration for a list of possible return values.
Remarks
This function initiates a synchronous search operation. The parameters and effects of this function include those of ldap_search_s. The extended routine includes additional parameters to support client and server controls and to specify size and time limits for each search operation.
You can use the ldap_set_option function with the ld session handle to set the LDAP_OPT_DEREF option that determines how the search is performed. Two other search options, LDAP_OPT_SIZELIMIT and LDAP_OPT_TIMELIMIT, are ignored in favor of the SizeLimit and TimeLimit option parameters in this function.
Upon completion of the search operation, ldap_search_ext_s returns to the caller. Use ldap_search_ext if you prefer to have the operation carried out asynchronously.
In a multithreading environment, calls to ldap_search_ext_s are thread-safe.
