asm() vs. scratch register

I'm wondering is there any restriction in using registers when using the inline assembly function ask() in a C routine?

When writing an assembly function called by a C program there is the group of scratch registers and the group of non-scratch registers which need to be saved and restored. Therefore, is there such a restriction for asm(), too or can I just use any register I want and the compiler cares for the rest?
