Detailed Description

The iovec class inherits the saga::buffer class, and three additional state attributes: offset, len in and len out.

With that addition, the new class can be used very much the same way as the iovec structure defined by POSIX for readv/writev, with the buffer len_in being interpreted as the POSIX iov_len, i.e. the number of bytes to read/write.
