2 | * @brief Check the behaviour of rtems_bdbuf_read() function |
---|
3 | * with different reports from disk device driver. |
---|
4 | * |
---|
5 | * Test sequence: |
---|
6 | * -# Call rtems_bdbuf_read() function and return 0 from disk device |
---|
7 | * driver ioctl() function, and the result of asynchronous read |
---|
8 | * complete notification is successful. |
---|
9 | * -# Check that rtems_bdbuf_read() returns RTEMS_SUCCESSFUL and |
---|
10 | * provides buffer descriptor. |
---|
11 | * -# Call rtems_bdbuf_read() function and return -1 from disk device |
---|
12 | * driver ioctl() function (there will be no asynchronous read |
---|
13 | * complete notification). |
---|
14 | * -# Check that rtems_bdbuf_read() returns RTEMS_IO_ERROR. |
---|
15 | * -# Call rtems_bdbuf_read() function and return 0 from disk device |
---|
16 | * driver ioctl() function, but the result of asynchronous read |
---|
17 | * complete notification is faulty (with some erroneous status). |
---|
18 | * -# Check that rtems_bdbuf_read() returns that status and does not |
---|
19 | * return buffer descriptor. |
