Compile error: parameter name omitted

Hi team.

I compile the project in fedora 42 with gcc 15.2 failed https://github.com/microsoft/ntttcp-for-linux/pull/97. But do well in ubuntu 24.04 with gcc 13.3.

I',m commit https://github.com/microsoft/ntttcp-for-linux/commit/e18597c05e3d4b439849ce0e149cb701ff5a36c2 recently, but the CI failed due to "parameter name omitted" in aarch64 ci. Upon checking some documentation, I found some issues that require your decision.

1. use __attribute__((unused)) , but it depends compiler.
2. use [[maybe_unused]] , but it depends c23.
3. use (void) unused, but add extra code.

In my opinion, the third option is optimal. While it adds some extra code, it maintains full compatibility with different compilers and language versions. However, since this touches on coding style (specifically, the recommended practice of using macros for unused variables), the final decision should be left to your team's discretion.

Ok, I see fix approved https://github.com/microsoft/ntttcp-for-linux/pull/100 .

Start by reviewing commit e18597c05e3d4b439849ce0e149cb701ff5a36c and the linked aarch64 CI failure to understand the omitted-parameter error. Check pull request #100 for the approved fix; the issue is done when the project compiles successfully across the affected compiler and CI configurations.
