It then calls the function BUILTINSC_GetFunctionList exposed 16 // (internally to the linkage in question) by builtins. This enables 17 // the build system to ultimately turn builtins into a shared library 18 // that exposes a C_GetFunctionList function, meaning it can be used as a 19 // PKCS#11 module. 20 21 CK_RV BUILTINSC_GetFunctionList(CK_FUNCTION_LIST_PTR_PTR ppFunctionList); 22 23 CK_RV C_GetFunctionList(CK_FUNCTION_LIST_PTR_PTR ppFunctionList) { 24 return BUILTINSC_GetFunctionList(ppFunctionList); 25 } 26 27 // On MinGW there's a toolchain mismatch that results in _Unwind_Resume being 28 // undefined.
