Could someone please explain what the effect of splice() is supposed to be? Is it just a faster way for the kernel to move data from one place to another? Is this something that programs would use or would it be something that other parts of the kernel use? I see that it has fdin and fdout as arguments. Does that mean that it uses file descriptors and can be used for copying files? I don't know anything about kernel development so I'm trying to put this feature into context.
