void io_uring_prep_splice(io_uring_sqe *  sqe,  int  fd_in,  ulong  off_in,

pure @system

Prepare an SQE for a SPLICE operation.

Moves data between two file descriptors without copying through user space. At least one of fd_in or fd_out must be a pipe.

Parameters

`sqe`	Pointer to the SQE to prepare.
`fd_in`	Input file descriptor.
`off_in`	Input offset (`cast(ulong)-1` for current position).
`fd_out`	Output file descriptor.
`off_out`	Output offset (`cast(ulong)-1` for current position).
`len`	Number of bytes to splice.
`flags`	Splice flags (SPLICE_F_*).
`user_data`	User data to be returned with the completion.
