/* Description:
|
|
* Verify that:
|
|
* 1) renameat2(2) returns -1 and sets errno to EEXIST because newpath
|
|
* already exists and the flag RENAME_NOREPLACE is used.
|
|
* 2) renameat2(2) returns 0.
|
|
* 3) renameat2(2) returns -1 and sets errno to ENOENT because the flag
|
|
* RENAME_EXCHANGE is used and newpath does not exist.
|
|
* 4) renameat2(2) returns 0 because the flag RENAME_NOREPLACE is used,
|
|
* both olddirfd and newdirfd are valid and oldpath exists and
|
|
* newpath does not exist.
|
|
* 5) renameat2(2) returns -1 and sets errno to EINVAL because
|
|
* RENAME_NOREPLACE and RENAME_EXCHANGE are used together
|
|
* 6) renameat2(2) returns -1 and sets errno to EINVAL because
|
|
* RENAME_WHITEOUT and RENAME_EXCHANGE are used together
