CallEnclave function (enclaveapi.h)
Calls a function within an enclave. CallEnclave can also be called within an enclave to call a function outside of the enclave.
Syntax
BOOL CallEnclave(
[in] LPENCLAVE_ROUTINE lpRoutine,
[in] LPVOID lpParameter,
[in] BOOL fWaitForThread,
[out] LPVOID *lpReturnValue
);
Parameters
[in] lpRoutine
The address of the function that you want to call.
[in] lpParameter
The parameter than you want to pass to the function.
[in] fWaitForThread
TRUE if the call to the specified function should block execution until an idle enclave thread becomes available when no idle enclave thread is available. FALSE if the call to the specified function should fail when no idle enclave thread is available.
This parameter is ignored when you use CallEnclave within an enclave to call a function that is not in any enclave.
[out] lpReturnValue
The return value of the function, if it is called successfully.
