// The build system builds the rust library builtins as a static library
|
|
// called builtins_static. On macOS and Windows, that static library can
|
|
// be linked with an empty file and turned into a shared library with the
|
|
// function C_GetFunctionList exposed.
|
|
// Unfortunately, on Linux, exposing the C_GetFunctionList in the static
|
|
// library doesn't work for some unknown reason. As a workaround, this file
|
|
// declares its own C_GetFunctionList that can be exposed in the shared
|
|
// library. It then calls the function BUILTINSC_GetFunctionList exposed
|
|
// (internally to the linkage in question) by builtins. This enables
|
|
// the build system to ultimately turn builtins into a shared library
|
|
// that exposes a C_GetFunctionList function, meaning it can be used as a
|
|
// PKCS#11 module.
