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