C (GEM)

Explanation of C (GEM)

C (GEM) refers to the C programming language with the GEM (Graphics Environment Manager) library. GEM is a graphical user interface (GUI) library for C programming, primarily used in the Atari ST computer system. It provides functions and tools for creating windows, menus, dialog boxes, and other graphical elements in C programs.

The GEM library allows developers to create visually appealing and interactive applications with a graphical interface. It simplifies the process of handling user input, displaying graphics, and managing windows and menus. By using GEM, developers can create applications that are more user-friendly and visually appealing.

To use C with GEM, developers need to include the appropriate GEM header files and link against the GEM library. They can then use the GEM functions and structures to create and manipulate graphical elements in their programs.

Here is an example of a simple C program that uses GEM to create a window:

#include <gem.h>

int main()
{
    int handle;
    int event;

    handle = graf_handle(&event);
    wind_open(10, 10, 300, 200, 1, 1);
    evnt_mesag(event);

    wind_close(handle);
    return 0;
}

In this example, the program includes the gem.h header file, which contains the necessary declarations for GEM functions. The main function creates a window using the wind_open function, specifying the position, size, and other parameters of the window. The evnt_mesag function waits for an event to occur, such as a mouse click or a key press. Finally, the wind_close function closes the window.

This is just a basic example to demonstrate the usage of GEM in C programming. GEM provides many more functions and features for creating complex graphical applications.

Note: The provided code example is a simple illustration and may not compile or run correctly without the necessary GEM library and setup.
