Subject: tests: fix dirent d_type support verification
|
|
|
f180de |
|
|
|
f180de |
* tests/d_type-check: Check also the d_type of files,
|
|
|
f180de |
which excludes XFS appropriately. Specify all argument
|
|
|
f180de |
and return types to avoid truncated pointers being passed,
|
|
|
f180de |
which skipped the test due to crashes on x86_64 at least.
|
|
|
f180de |
Simplify the C library lookup by reusing the interpreter's.
