WS_CERTIFICATE_VALIDATION_CALLBACK callback function (webservices.h)

  • Article

The WS_CERTIFICATE_VALIDATION_CALLBACK callback is invoked to validate a certificate when a connection to an HTTP server has been established and headers sent.

Syntax

WS_CERTIFICATE_VALIDATION_CALLBACK WsCertificateValidationCallback;

HRESULT WsCertificateValidationCallback(
  [in]           PCCERT_CONTEXT certContext,
  [in, optional] void *state
)
{...}

Parameters

[in] certContext

A pointer to a CERT_CONTEXT structure that is associated with the connection. Applications must free this structure using CertFreeCertificateContext.

[in, optional] state

A pointer to application specific state information. This parameter corresponds to the state member of the WS_CERTIFICATE_VALIDATION_CALLBACK_CONTEXT structure.

Return value

This callback function can return one of these values.

Return code Description
S_OK
 The certificate validated successfully.
Other Errors
This function may return other errors not listed above.

Remarks

If WS_CERTIFICATE_VALIDATION_CALLBACK returns any value other than S_OK, the channel will be aborted. The service proxy will also be aborted if this property was passed to WsCreateServiceProxy.

The callback implementation must avoid long computation times or long blocking calls so that it returns to the caller quickly.
