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.

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.
