Signal Handlign Examples 1. Capturing SIGINT This program demonstrates capturing the SIGINT signal (Ctrl+C) with a custom handler. #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <signal.h> void sigint_handler(int sig_num) { if (sig_num == SIGINT) { printf("Ctrl+C was pressed.\n&quot ...

Standardized Code Patterns for Varible Modification 1. Toggling Between 0 and 1 Use the XOR operator to switch a variable between 0 and 1 each time the code executes. DisplayModeFlag ^= 1; 2. Cycling Through a Range of Values Increment a variable and reset it to the starting value once it exceeds an upper limit. if (++DisplayModeFlag == LIMIT_ ...
