During an execve (2), the dispositions of handled signals are reset to the default; the The abort () function first unblocks the SIGABRT signal, and then raises that signal for the calling process (as though raise (3) was called). However, we can set up custom signal handlers to catch SIGABRT and perform custom actions such as logging required information or cleanup processes before termination of the program. h> and is part of the C/C++ standard library. The SIGABRT signal can be caught, but it cannot be blocked; if the signal handler returns Causes abnormal program termination unless SIGABRT is being caught by a signal handler passed to std::signal and the handler does not return.
