Thanks for quick response.

SGX does not declare any syscalls but it does have an ioctl API and
a vDSO.

I think one thing that the man page is missing is SIGSEGV handling.
When user space directly invokes ENCLU[EENTER], then the exceptions
inside are recognized through SIGSEV. This should be probably added,
and then "SEE ALSO" should point out to sigaction().
