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. 19 20 CK_RV TRUST_ANCHORS_GetFunctionList(CK_FUNCTION_LIST_PTR_PTR ppFunctionList); 21 22 CK_RV C_GetFunctionList(CK_FUNCTION_LIST_PTR_PTR ppFunctionList) { 23 return TRUST_ANCHORS_GetFunctionList(ppFunctionList); 24 } 25 26 // On MinGW there's a toolchain mismatch that results in _Unwind_Resume being 27 // undefined.
