cssm_GetAttachFunctions - Get SPI function table (CDSA)
# include <cdsa/cssm.h>
CSSM_RETURN CSSMAPI cssm_GetAttachFunctions (CSSM_MODULE_HANDLE
hAddIn, CSSM_SERVICE_MASK AddinType, void
**SPFunctions, CSSM_GUID_PTR Guid)
Common Security Services Manager library (libcssm.so)
The handle identifying the attach-session whose function
table is to be returned by this function. A CSSM_SERVICE_MASK
value identifying the type of service module
whose function table is to be returned by this function.
A pointer to the service module function table, which CSSM
acquired from the service module during module-attach processing.
The module manager should use this table to forward
application invocation of the elective APIs to their
corresponding SPIs. The memory pointed to by the function
pointers should not be freed by the EMM. A CSSM_GUID
value identifying the service module whose function table
is to be returned by this function.
This function returns an SPI function table for the service
module identified by the module handle. The module
must be of the type specified by the service mask. The
SPFunctions parameter contains the returned function
table. The elective module manager must use this function
table to forward an application's call to the elective
APIs to their corresponding SPIs represented in the function
table. The returned Guid identifies the service module.
It can be used to locate credentials and other information
about the service module.
This function sets a lock on the SP functions table. The
CSSM service function cssm_ReleaseAttachFunctions() must
be used to release the lock.
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 are described in the CDSA technical standard. See
