函数名称：gs_get_register() - get register value from its offset*@regs: pt_regs from which register value is gotten.*@offset: offset number of the register.* regs_get_register returns the value of a register. The @offset is the

函数原型：static inline unsigned long regs_get_register(struct pt_regs *regs, unsigned int offset)

返回类型：unsigned long

参数：

类型参数名称
struct pt_regs *regs
unsigned intoffset
216  如果此条件成立可能性小(为编译器优化)(offset > MAX_REG_OFFSET)则返回:0
220  如果offset恒等于offsetof(structpt_regs, cs)或offset恒等于offsetof(structpt_regs, ss)或offset恒等于offsetof(structpt_regs, ds)或offset恒等于offsetof(structpt_regs, es)或offset恒等于offsetof(structpt_regs, fs)或offset恒等于offsetof(structpt_regs, gs)则
226  返回:*regs加offset的和
230  返回:*regs加offset的和
