Cool get_user_pages question

Hi frenz ,

I came across get_user_pages() function . I found that this function is used when the there is no need of kernel buffering (buffer cache ) so the data from the device is directly placed in the userspace . But still i dont know when and how to use this function . Do anyone have some code snippets which tells me how the transfer is happening or any theory that tells how it happen which would be quite useful .. Thanks in advance
