函数名称:private llseek:* for a block special file file_inode(file)->i_size is zero* so we compute the size by hand (just as in block_read/write above)
函数原型:static loff_t block_llseek(struct file *file, loff_t offset, int whence)
返回类型:loff_t
参数:
类型 | 参数 | 名称 |
---|---|---|
struct file * | file | |
loff_t | offset | |
int | whence |
651 | bd_inode等于bdev_file_inode(file) |
654 | inode_lock(bd_inode) |
655 | retval等于xed_size_llseek - llseek implementation for fixed-sized devices*@file: file structure to seek on*@offset: file offset to seek to*@whence: type of seek*@size: size of the file |
656 | inode_unlock(bd_inode) |
657 | 返回:retval |
