How to detect the status of the capslock in linux programmatically?

In Linux, you can programmatically detect the status of the Caps Lock key by reading the state of the relevant keyboard LED. Here's a step-by-step guide on how to achieve this using the C programming language:

1. Include the necessary header files at the beginning of your source code: #include
2. Implement the following function to query the Caps Lock status: int isCapsLockOn(Display* display) { XKeyboardState xkb; XGetKeyboardControl(display, &xkb); return (xkb.led_mask & (1 << 0)); // The first bit corresponds to Caps Lock (0 indexed) }
3. In your main function, open a connection to the X display server and call the isCapsLockOn function to check the Caps Lock status: int main() { Display* display = XOpenDisplay(NULL); // Open a connection to the X display server int capsLockOn = isCapsLockOn(display); printf("Caps Lock status: %s ", capsLockOn ? "ON" : "OFF"); XCloseDisplay(display); // Close the connection to the X display server return 0; }
4. Compile the code: gcc -o capslock_status_capslock status.c -lX11
5. Run the compiled program to get the Caps Lock status: ./capslock_status

The program will output "Caps Lock status: ON" or "Caps Lock status: OFF" based on the Caps Lock key's state.
