SYNOPSIS

# include <cssm.h>

CSSM_RETURN CSSMAPI cssm_GetModuleInfo
(CSSM_MODULE_HANDLE Module,
CSSM_GUID_PTR Guid,
CSSM_VERSION_PTR Version,
uint32 *SubServiceId,
CSSM_SERVICE_TYPE *SubServiceType,
CSSM_ATTACH_FLAGS *AttachFlags,
CSSM_KEY_HIERARCHY *KeyHierarchy,
CSSM_API_MEMORY_FUNCS_PTR AttachedMemFuncs,
CSSM_FUNC_NAME_ADDR_PTR FunctionTable,
uint32 NumFunctionTable);

PARAMETERS

`Module` (`input`)		The handle to a service provider module.
`GUID` (`input`)		A pointer to the CSSM_GUID structure containing the global unique identifier for this module.
`Version` (`output`)		The version number set on ModuleAttach.
`SubServiceId` (`output`)
		The slot number of the reader to which the module is attached.
`SubServiceType` (`output`)
		A CSSM_SERVICE_TYPE value identifying the class of security service.
`AttachFlags` (`output`)
		This parameter provides the caller with session specific information associated with the module handle.
`KeyHierarchy` (`output`)
		The key hierarchy supplied when the module was attached.
`AttachedMemFuncs` (`output`)
		The memory functions supplied when the module was attached.
`FunctionTable` (input/output optional)
		A table of function-name and API function-pointer pairs. The caller provides the name of the functions as input. The corresponding API function pointers are returned on output. The function table allows dynamic linking of CDSA interfaces, including interfaces to Elective Module Managers, which are transparently loaded by CSSM during the `CSSM_ModuleAttach`() function. The caller of this function should allocate the memory for the number of slots required.
`NumFunctionTable` (`input`)
		The number of entries in the FunctionTable parameter. If no FunctionTable is provided, this value must be zero.

DESCRIPTION

This function returns the state information associated with the module handle. The information returned by this function is that set by the call to the CSSM_ModuleAttach() function. The entry point to this function is provided to a service module in a table of upcall functions passed to the service provider during module attach processing.

If the PVC checking for service providers is on, the service provider has to introduce itself before calling this function.

RETURN VALUE

A CSSM_RETURN value indicating success or specifying a particular error condition. The value CSSM_OK indicates success. All other values represent an error condition.

ERRORS

Errors are described in the CDSA Technical Standard.
