The PFN_CRYPT_XML_CREATE_TRANSFORM callback function creates a transform for a specified data provider.
Syntax
HRESULT CALLBACK PFN_CRYPT_XML_CREATE_TRANSFORM( __in const CRYPT_XML_ALGORITHM *pTransform, __in CRYPT_XML_DATA_PROVIDER *pProviderIn, __out CRYPT_XML_DATA_PROVIDER *pProviderOut );
Parameters
- pTransform [in]
-
A CRYPT_XML_ALGORITHM structure that specifies the transform to apply.
- pProviderIn [in]
-
A pointer to a CRYPT_XML_DATA_PROVIDER structure that specifies the data provider to use as input for the transform.
- pProviderOut [out]
-
A pointer to a CRYPT_XML_DATA_PROVIDER structure to receive the data provider of the transform.
Return value
If the function succeeds, the function returns zero.
If the function fails, it returns an HRESULT value that indicates the error.
Remarks
In the transform chain, the output of a transform is the input of the next transform in the chain. The implementation of the callback function is responsible for calling the provider close function on the input transform to release the input provider.
