This function searches the LDAP directory and returns a requested set of attributes for each entry matched.

Syntax 

ULONG ldap_search_s(
  LDAP* 
ld,
  UNICODE PTCHAR 
base,
  ULONG 
scope,
  UNICODE PTCHAR 
filter,
  UNICODE PTCHAR 
attrs[],
  ULONG 
attrsonly,
  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.

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 Value

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_RETCODEenumeration for a list of possible return values.

Remarks

This function initiates a synchronous search operation.

You can use the ldap_set_optionfunction with the ldsession 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_sreturns to the caller. Use ldap_searchif you prefer to have the operation carried out asynchronously.

In a multithreading environment, calls to ldap_search_sare thread-safe.

Requirements

Header winldap.h
Library wldap32.lib
Windows Embedded CE Windows CE .NET 4.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
