Struct ucp_dt_iov

#[repr(C)]
pub struct ucp_dt_iov {
    pub buffer: *mut c_void,
    pub length: size_t,
}

@ingroup UCP_DATATYPE @brief 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 @a length is zero, the memory pointed to by @a buffer will not be accessed. Otherwise, @a buffer must point to valid memory.

Fields

buffer: *mut c_void

< Pointer to a data buffer

length: size_t

< Length of the @a buffer in bytes
