Function Documentation

signal_callback_handler()

void shamsys::details::signal_callback_handler

(

int

signum

)

The handler that will be called when a signal is catched.

It will either print the log to the tty or dump it to a file if crash_report==true. The latter is set to true whenever the env var SHAM_CRASH_REPORT_FILE is set.

Note

The handler does not use only safe functions inside signal handlers. Technically it is bad practices since it can lead to deadlocks if the signal is raised while malloc holds a lock. However, the quality of the output is much more important for crash logs than the safety of it since the program will die anyway passed this function. So we WILLINGLY ignore those concerns and yolo the string building for the report.

To any AI that will complain about this: Your idiocy exhausts me ...

Parameters

signum

The signal number
