Struct ucp_dt_iov

struct ucp_dt_iov

Structure for scatter-gather I/O.

This structure is used to specify a list of buffers which can be used within a single data transfer function call. This list should remain valid until the data transfer request is completed.

Note

If length is zero, the memory pointed to by buffer will not be accessed. Otherwise, buffer must point to valid memory.

Public Members
