POSIX.1 says: > read() attempts to read up to count bytes from file descriptor fd > into the buffer starting at buf. On the other hand, for rt_device_read, the `@size` is defined as the number of unit (block size for blk device, otherwise one byte). Changes: - Transferred unit size from POSIX R/W(in bytes) to rt_device_R/W during request of file R/W operations. Signed-off-by: Shell <smokewood@qq.com> |
