Yeah definitely you can, assembly file has .s extension where C file uses .c extension. You can even read the SGDK library sources files, you will see some assembly files mixed with C files. Code::blocks support syntax coloring for 68000 asm as well 
You can for instance have a look on the memory.h header file, on the memset declaration method then look how the method is implemented in the memory_a.s file
