dcgmi InstallCtrlHandler unhandled return

[nfisher]

Description

In dcgmi the InstallCtrlHandler silently ignores the return codes in

DCGM/dcgmi/main_dcgmi.cpp

Line 78 in e137795

InstallCtrlHandler();

.

Expected Behaviour

The return value of InstallCtrlHandler should be validated. If the installation fails, the code should:

• Log an error with sufficient context.
• Avoid continuing execution in an invalid state.

Actual Behavior

The function is invoked without checking its return value, so failures are ignored.

Why This Matters

Failing to install a control handler can prevent proper signal handling (e.g., shutdown, interrupts). Ignoring the result:

• Obscures root causes during failures.
• May lead to resource leaks or improper shutdown.
• Violates standard error-handling practices.
