First, the authors describe basic usage syntax for inline assembly (inline asm) embedded within C and C++ programs. Then they explain intermediate concepts, such as addressing modes, the clobbers list, and branching stanzas, as well as more advanced topics, such as memory clobbers, the volatile attribute, and locks are discussed for those who want to use inline asm in multithreaded applications. See the article here.
