DRMGetIssuanceLicenseTemplate function

[The AD RMS SDK leveraging functionality exposed by

the client in Msdrm.dll is available for use in Windows Server 2008, Windows Vista, Windows Server 2008 R2, Windows 7, Windows Server 2012, and Windows 8. It may be altered or

The DRMGetIssuanceLicenseTemplate function obtains an issuance license template from an existing issuance license.

Syntax

DRMEXPORT HRESULT UDAPICALL DRMGetIssuanceLicenseTemplate(
  IN DRMPUBHANDLE hIssuanceLicense,
  IN OUT UINT     *puIssuanceLicenseTemplateLength,
  PWSTR           wszIssuanceLicenseTemplate
);

Parameters

hIssuanceLicense

The handle of the issuance license to create a template from.

puIssuanceLicenseTemplateLength

A pointer to a UINT value that, on entry, contains the length, in characters, of the wszIssuanceLicenseTemplate buffer. This length must include the terminating null character.

After the function returns, this value contains the number of characters, including the terminating null character, that were copied to the wszIssuanceLicenseTemplate buffer.

wszIssuanceLicenseTemplate

A pointer to a null-terminated Unicode string that receives the issuance license template XrML. The size of this buffer is specified by the puIssuanceLicenseTemplateLength parameter.

To determine the required size of this buffer, pass NULL for this parameter. The function will place the size, in characters, including the terminating null character, in the puIssuanceLicenseTemplateLength value.

Return Value

If the function succeeds, the function returns S_OK.

If the function fails, it returns an HRESULT value that indicates the error. Possible values include, but are not limited to, those in the following list. For a list of common error codes, see Common HRESULT Values.

Remarks

This function is used to extract a XrML string version of an issuance license when you have a handle to an existing issuance license. This string can then be used as a template to create a new issuance license. To create a new template, first create a blank issuance license by calling DRMCreateIssuanceLicense (working from a prior template or not), then add custom rights, users, or other information to the issuance license. Pass the modified issuance license to this function and extract the template.

Memory allocation and release for out parameters is the responsibility of the calling function. To obtain the size needed to hold the template string, call this function with NULL in the wszIssuanceLicenseTemplate parameter to retrieve the required size in the puIssuanceLicenseTemplateLength parameter.

The issuance license passed in to DRMGetIssuanceLicenseTemplate must have metadata and associated rights. If it does not, the function call will fail. Use the DRMSetMetaData function to set metadata for an issuance license. Use the DRMCreateRight or DRMAddRightWithUser functions to create or add rights.
