      8 // The build system builds the rust library test_trust_anchors as a static
      9 // library called test_trust_anchors_static. On macOS and Windows, that static
     10 // library can be linked with an empty file and turned into a shared library
     11 // with the function C_GetFunctionList exposed. Unfortunately, on Linux,
     12 // exposing the C_GetFunctionList in the static library doesn't work for some
     13 // unknown reason. As a workaround, this file declares its own C_GetFunctionList
     14 // that can be exposed in the shared library. It then calls the function
     15 // TRUST_ANCHORS_GetFunctionList exposed (internally to the linkage in question)
     16 // by trust-anchors. This enables the build system to ultimately turn
     17 // trust-anchors into a shared library that exposes a C_GetFunctionList
     18 // function, meaning it can be used as a PKCS#11 module.
