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:
- Include the necessary header files at the beginning of your source code:
#include
- 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)
}
- 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;
}
- Compile the code:
gcc -o capslock_status_capslock status.c -lX11
- 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.
