In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).
The signal is usually initiated by the process itself when it calls abort() function of the C Standard Library, but it can be sent to the process from outside like any other signal. SIGIOT indicates that the CPU has executed an explicit "trap" instruction (without a defined function), or an unimplemented instruction (when emulation is unavailable).

The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library , which is a superset of it. [ 3 ]
The C POSIX library is a specification of a C standard library for POSIX systems. It was developed at the same time as the ANSI C standard. Some effort was made to make POSIX compatible with standard C; POSIX includes additional functions to those introduced in standard C. On the other hand, the 5 headers that were added to the C standard ...
setjmp.h is a header defined in the C standard library to provide "non-local jumps": control flow that deviates from the usual subroutine call and return sequence. The complementary functions setjmp and longjmp provide this functionality.

The POSIX standard requires that the sigaction structure be defined as below in the <signal.h> header file and it should contain at least the following fields: struct sigaction { void ( * sa_handler )( int ); /* address of signal handler */ sigset_t sa_mask ; /* additional signals to block */ int sa_flags ; /* signal options */ /* alternate ...
