* Description:
|
|
* Verify that,
|
|
* 1) splice() returns -1 and sets errno to EBADF if the file
|
|
* descriptor fd_in is not valid.
|
|
* 2) splice() returns -1 and sets errno to EBADF if the file
|
|
* descriptor fd_out is not valid.
|
|
* 3) splice() returns -1 and sets errno to EBADF if the file
|
|
* descriptor fd_in does not have proper read-write mode.
|
|
* 4) splice() returns -1 and sets errno to EINVAL if target
|
|
* file is opened in append mode.
|
|
* 5) splice() returns -1 and sets errno to EINVAL if neither
|
|
* of the descriptors refer to a pipe.
|
|
* 6) splice() returns -1 and sets errno to ESPIPE if off_in is
|
|
* not NULL when the file descriptor fd_in refers to a pipe.
|
|
* 7) splice() returns -1 and sets errno to ESPIPE if off_out is
|
|
* not NULL when the file descriptor fd_out refers to a pipe.
