函数名称：getreg

函数原型：static unsigned long getreg(struct task_struct *task, unsigned long offset)

返回类型：unsigned long

参数：

类型参数名称
struct task_struct *task
unsigned longoffset
413  当:offset恒等于offsetof(structuser_regs_struct, cs)
414  当:offset恒等于offsetof(structuser_regs_struct, 取寄存器值(ds))
415  当:offset恒等于offsetof(structuser_regs_struct, es)
416  当:offset恒等于offsetof(structuser_regs_struct, 取寄存器值(fs))
417  当:offset恒等于offsetof(structuser_regs_struct, 取寄存器值(gs))
418  当:offset恒等于offsetof(structuser_regs_struct, ss)
419  返回:get_segment_reg(task, offset)
421  当:offset恒等于offsetof(structuser_regs_struct, flags)
422  返回:get_flags(task)
425  当:offset恒等于offsetof(structuser_regs_struct, fs_base)
426  返回:Read/write a task's FSBASE or GSBASE. This returns the value that* the FS/GS base would have (if the task were to be resumed). These* work on the current task or on a non-running (typically stopped* ptrace child) task.
427  当:offset恒等于offsetof(structuser_regs_struct, gs_base)
428  返回:x86_gsbase_read_task(task)
432  返回:pt_regs_access(task_pt_regs(task), offset)
