Commit Message

Muhammad Usama Anjum March 5, 2024, 6:08 a.m. UTC
Conform the layout, informational and status messages to TAP. No
functional change is intended other than the layout of output messages.

Changes since v4:
- close fds correctly with code changes added in v3

Chanages since v3:
- abort test-case instead of exiting if heap/mem allocation fails
- Correct test_alloc_zeroed() test case in case of failure

Changes since v2:
- Minor improvements in test_alloc_zeroed() results

Changes since v1:
- Update some more error handling code

t would be nice to improve the error messages in addition to
changing them over to TAP format. Please see below:

Why not include the return value in the message?
