This function searches the LDAP directory and returns a requested set of attributes for each entry matched.
ULONG ldap_search_s(LDAP* ld,UNICODE PTCHARbase,ULONGscope,UNICODE PTCHARfilter,UNICODE PTCHARattrs[],ULONGattrsonly,LDAPMessage** res);
Parameters
- ld
[in] Session handle. - base
[in] Distinguished name of the entry at which to start the search. - scope
[in] Specifies a value to indicate the scope of the search. The following table shows the possible values.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. For more information. - attrs
[in] Null-terminated array of strings indicating the 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. - res
[out] Contains the results of the search upon completion of the call.
Return Values
If this function succeeds, the return value is LDAP_SUCCESS.
If this function fails, it returns an error code; however, this function can fail and can still allocate pMsg. See the example below for handling this behavior. See the LDAP_RETCODE enumeration for a list of possible return values.
Remarks
This function initiates a synchronous search operation.
You can use the ldap_set_option function with the ld session handle to set the LDAP_OPT_SIZELIMIT, LDAP_OPT_TIMELIMIT, and LDAP_OPT_DEREF options that determine how the search is performed.
Upon completion of the search operation, ldap_search_s returns to the caller. Use ldap_search if you prefer to have the operation carried out asynchronously.
In a multithreading environment, calls to ldap_search_s are thread-safe.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Winldap.h.
Link Library: Wldap32.lib.
