ldap_add_sW function (winldap.h)

The ldap_add_s function initiates a synchronous add operation that adds an entry to a tree. The parent of the entry being added must already exist or the parent must be empty (equal to the root distinguished name) for an add operation to succeed.


  [in] LDAP          *ld,
  [in] PWSTR         dn,
  [in] LDAPModW * [] attrs


[in] ld

The session handle.

[in] dn

A pointer to a null-terminated string that contains the distinguished name of the entry to add.

[in] attrs

A null-terminated array of pointers to LDAPMod structures. Each structure specifies a single attribute. See Remarks for more information.

Return value

If the function succeeds, the return value is LDAP_SUCCESS.

If the function fails, it returns an error code. See Return Values for more information.


Before calling ldap_add_s. you must create an entry by specifying its attributes in LDAPMod structures. Set the mod_op member of each structure to LDAP_MOD_ADD, and set the mod_type and mod_vals members as appropriate for your entry. See Modifying a Directory Entry for more information.

Upon completion of the add operation, ldap_add_s returns to the caller. Use ldap_add if you prefer to have the operation carried out asynchronously.

Multithreading: Calls to ldap_add_s are thread-safe.

Note  When connecting to an LDAP 2 server, the application must perform a bind operation (by calling one of the ldap_bind or ldap_simple_bind routines) before attempting any other operations.


The winldap.h header defines ldap_add_s as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
