+// The build system builds the rust library ipcclientcerts as a static library
+// called ipcclientcerts_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. This allows that shared library to be
+// used as a PKCS#11 module (see osclientcerts).
+// 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 IPCCC_GetFunctionList exposed
+// (internally to the linkage in question) by ipcclientcerts. This enables
+// the build system to ultimately turn ipcclientcerts into a shared library
+// that exposes a C_GetFunctionList function, meaning it can be used as a
+// PKCS#11 module.
