|
* Test Name: preadv02
|
|
*
|
|
* Description:
|
|
* 1) preadv(2) fails if iov_len is invalid.
|
|
* 2) preadv(2) fails if the vector count iovcnt is less than zero.
|
|
* 3) preadv(2) fails if offset is negative.
|
|
* 4) preadv(2) fails when attempts to read into a invalid address.
|
|
* 5) preadv(2) fails if file descriptor is invalid.
|
|
* 6) preadv(2) fails if file descriptor is not open for reading.
|
|
* 7) preadv(2) fails when fd refers to a directory.
|
|
* 8) preadv(2) fails if fd is associated with a pipe.
|
|
*
|
|
* Expected Result:
|
|
* 1) preadv(2) should return -1 and set errno to EINVAL.
|
|
* 2) preadv(2) should return -1 and set errno to EINVAL.
|
|
* 3) preadv(2) should return -1 and set errno to EINVAL.
|
|
* 4) preadv(2) should return -1 and set errno to EFAULT.
|
|
* 5) preadv(2) should return -1 and set errno to EBADF.
|
|
* 6) preadv(2) should return -1 and set errno to EBADF.
|
|
* 7) preadv(2) should return -1 and set errno to EISDIR.
|
|
* 8) preadv(2) should return -1 and set errno to ESPIPE.
