Proto:static int genregs_get(struct task_struct *target, const struct user_regset *regset, unsigned int pos, unsigned int count, void *kbuf, void __user *ubuf)

Type:int

Parameter:

TypeParameterName
struct task_struct *target
const struct user_regset *regset
unsigned intpos
unsigned intcount
void *kbuf
void __user *ubuf
440  If kbuf Then
441  k = kbuf
442  When count >= size of k cycle
443  k++ = getreg(target, pos)
444  count -= size of k
445  pos += size of k
447  Else
448  __user * u = ubuf
449  When count >= size of u cycle
450  If Write a simple value into user space, with less checking(getreg(target, pos), u++) Then Return -EFAULT
452  count -= size of u
453  pos += size of u
457  Return 0
