| //! The Intel(R) Software Guard Extensions SDK already supports mutex and conditional |
| //! variable synchronization mechanisms by means of the following APIand data types |
| //! defined in the Types and Enumerations section. Some functions included in the |
| //! trusted Thread Synchronization library may make calls outside the enclave (OCALLs). |
| //! If you use any of the APIs below, you must first import the needed OCALL functions |
| //! from sgx_tstdc.edl. Otherwise, you will get a linker error when the enclave is |
| //! being built; see Calling Functions outside the Enclave for additional details. |
| //! The table below illustrates the primitives that the Intel(R) SGX Thread |
| //! Synchronization library supports, as well as the OCALLs that each API function needs. |
