A Signal Handler Entry Point warning is issued at every code location corresponding to a modeled signal handler entry point.
This class is provided for diagnostic purposes and does not (necessarily) correspond to vulnerabilities in the code. There are several cases in which it can be helpful to enable the Signal Handler Entry Point class.
| Class Name | Signal Handler Entry Point |
|---|---|
| Significance | diagnostic |
| Mnemonic | DIAG.SIGHAND.ENTRY |
| Categories | None |
| Availability | Available for C and C++. |
| Enabling | Checks for this warning class are
disabled by default. To enable them, add the following WARNING_FILTER
rule to the project configuration file.
WARNING_FILTER += allow class="Signal Handler Entry Point" This class is for analysis diagnostics, rather than for warning about issues in your code. As such, it is generally not enabled by CodeSonar presets. In particular, it is not enabled by the all_warningclasses preset. |

}
Signal Handler Entry Point warnings can be triggered by any function treated as a signal handler entry point function by CodeSonar:
