Execute sleep() inside an enclave

[Shredha_K_]

Hi,

Is it possible to execute a sleep() inside an enclave. 

Thanks in advance

Hi,

Os calls(sleep()) cannot be used directly inside the enclave. We can use an OCALL to execute them.

Thank you Anusha :)

OCALL may not safe since the sleep action will be performed by untrusted part​, so I implemented sleep by using "sgx_get_trusted_time"

I think If you really need this, just make an OCALL. But in this way the time sleep()ed may not be accurate.
