SpUserModeInitializeFn callback function (ntsecpkg.h)
The SpUserModeInitialize function is called when a security support provider/authentication package (SSP/AP) DLL is loaded into the process space of a client/server application. This function provides the SECPKG_USER_FUNCTION_TABLE tables for each security package in the SSP/AP DLL.
Syntax
SpUserModeInitializeFn Spusermodeinitializefn;
NTSTATUS Spusermodeinitializefn(
[in] ULONG LsaVersion,
[out] PULONG PackageVersion,
[out] PSECPKG_USER_FUNCTION_TABLE *ppTables,
[out] PULONG pcTables
)
{...}
Parameters
[in] LsaVersion
The version of the security provider DLL (either Secur32.dll or Security.dll).
[out] PackageVersion
Pointer that returns the version of the SSP/AP DLL.
[out] ppTables
Pointer that returns an array of SECPKG_USER_FUNCTION_TABLE structures. Each structure is a table of pointers to the user-mode functions implemented by a security package deployed in the SSP/AP DLL.
[out] pcTables
Pointer that returns the number of elements in the array pointed to by the ppTables parameter.
Return value
If the function succeeds, return STATUS_SUCCESS.
If the function fails, return an NTSTATUS code that indicates the reason it failed.
Remarks
The SpUserModeInitialize function must be implemented by SSP/AP DLLs that contain user-mode security packages.
The ppTables parameter should contain one SECPKG_USER_FUNCTION_TABLE for each user-mode security package deployed in the DLL. For more information on deploying security packages in DLLs, see User Mode Initialization.
