LIBRARYCommon Security Services Manager library (cdsa$incssm300_shr.exe) API PARAMETERS
CCHandle (input)
The handle that describes the context of this cryptographicoperation.
PassThroughId (input)
An identifier specifying the custom function tobe performed.
InData (input)
A pointer to a module, implementation-specific structurecontaining the input data.
OutData (output)
A pointer to a module, implementation-specific structurecontaining the output data. The service provider will allocate thememory for this structure. The application should free the memoryfor the structure.
SPI PARAMETERS
CSPHandle (input)
Handle of the CSP supporting the PassThrough function.
Context (input)
Pointer to CSSM_CONTEXT structure that describesthe attributes with this custom context structure.
DESCRIPTIONThe CSSM_CSP_PassThrough() (CSSM API), or CSP_PassThrough() (CSP SPI), function is provided to allow CSP developersto extend the crypto functionality of the CSSM API. NOTESThe CSP_EventNotify() function is used by the CSSM Core to interact with theCSP module.
Because this function is only exposed to CSSM as a functionpointer, the function name internal to the CSP can be assigned atthe discretion of the CSP module developer. However, the parameterlist and return value types must match those defined for this function.
The error codes given in this section constitute the genericerror codes, which may be used by all CSP libraries to describecommon error conditions. CSP module developers may also define theirown module-specific error codes.
RETURN VALUEA CSSM_RETURN value indicating success or specifying a particularerror condition. The value CSSM_OK indicates success. All othervalues represent an error condition. ERRORSErrors are described in the CDSA Technical Standard.
