[in] UINT32 fixedDocumentIndex,
[out, retval] IXpsSignatureBlock **signatureBlock
);
Parameters
[in] partName
A pointer to the IOpcPartUri interface that contains the URI of the new part. For the method to generate a part name, this parameter can be set to NULL.
[in] fixedDocumentIndex
The index value of the FixedDocument part with which the new signature block is to be associated.

Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the table that follows. For return values that are not listed in this table, see XPS Digital Signature API Errors and XPS Document Errors.

The method succeeded. |

fixedDocumentIndex references a fixed document that is not found in the XPS package. |

Remarks
A signature block represents a SignatureDefinitions part in an XPS package. According to section 10.2.2 in the XML Paper Specification, zero or more SignatureDefinitions parts can be attached to each FixedDocument. This method creates a new SignatureDefinitions part with the specified name, links it from the specified FixedDocument part by a relationship, creates a new IXpsSignatureBlock interface, and adds this new interface to the internal signature block collection.
To retrieve a signature block, call the GetSignatureBlocks method.
