ldap_create_vlv_controlA function (winldap.h)
The ldap_create_vlv_control function is used to create the request control (LDAP_CONTROL_VLVREQUEST) on the server.
Syntax
WINLDAPAPI INT LDAPAPI ldap_create_vlv_controlA(
[in] PLDAP ExternalHandle,
[in] PLDAPVLVInfo VlvInfo,
[in] UCHAR IsCritical,
[out] PLDAPControlA *Control
);
Parameters
[in] ExternalHandle
An LDAP session handle, as obtained from a call to ldap_init.
[in] VlvInfo
The address of an LDAPVLVInfo structure whose contents are used to construct the value of the control created.
[in] IsCritical
If this value is not zero, the control created will have its criticality set to TRUE.
[out] Control
A result parameter assigned the address of an LDAPControl structure that contains the request control (LDAP_CONTROL_VLVREQUEST) created by this function.
Return value
The ldap_create_vlv_control function returns an LDAP error code to indicate failure, or LDAP_SUCCESS if successful.
Remarks
When a VLV search is conducted, the client must use this function to create a new VLV control that can be included in the search request sent to the server. The server will assign a contextID for this VLV search, passed to the client. When the VLV search is completed, you should use ldap_control_free to free the control returned by ldap_create_vlv_control, and ldap_controls_free to free the array of controls, including the VLV response control, returned by ldap_parse_result.

Note
The winldap.h header defines ldap_create_vlv_control 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.
