函数名称:snapshot_compat_ioctl
函数原型:static long snapshot_compat_ioctl(struct file *file, unsigned int cmd, unsigned long arg)
返回类型:long
参数:
类型 | 参数 | 名称 |
---|---|---|
struct file * | file | |
unsigned int | cmd | |
unsigned long | arg |
410 | 当:cmd恒等于SNAPSHOT_GET_IMAGE_SIZE |
411 | 当:cmd恒等于SNAPSHOT_AVAIL_SWAP_SIZE |
412 | 当:cmd恒等于SNAPSHOT_ALLOC_SWAP_PAGE |
418 | old_fs等于获取当前进程地址空间上限() |
419 | 设置寄存器值(fs) |
420 | err等于snapshot_ioctl(file, cmd, (unsignedlong) & offset) |
421 | 设置寄存器值(fs) |
424 | 返回:err |
427 | 当:cmd恒等于SNAPSHOT_CREATE_IMAGE |
431 | 当:cmd恒等于SNAPSHOT_SET_SWAP_AREA |
438 | err等于Careful: we have to cast the result to the type of the pointer* for sign reasons(offset, & offset) |
439 | err或等于Careful: we have to cast the result to the type of the pointer* for sign reasons(dev, & dev) |
442 | old_fs等于获取当前进程地址空间上限() |
443 | 设置寄存器值(fs) |
444 | err等于snapshot_ioctl(file, SNAPSHOT_SET_SWAP_AREA, (unsignedlong) & swap_area) |
446 | 设置寄存器值(fs) |
447 | 返回:err |
450 | 默认 |
451 | 返回:snapshot_ioctl(file, cmd, arg) |
