Some C function malloc-ed memory. This memory should be freeed

free this memory using something like addRoot(for instance) or
else or the true way is to copy malloc-ed memory to
gc-allocated memory and free malloc-ed memory at once? Like:
ubyte data* = cfunction_allocates_memory();
auto gcmemory = data[0..length(data)];
cfunction_frees_memory(data);
// work with gcmemory only
or
ubyte data* = cfunction_allocates_memory();
GC.someUnknownToMeFunction(data); // now gc will control this
memory
No.
Only free can be used with malloc. The memory comes from distinct
pools.
Another option could be to use "GC.malloc", and memcpy your old
mmory into your new memory, free the old memory, and use your new
block. GC.malloc, as the name suggests, is a malloc, but done by
the GC.
