MiniLibX :

A simple X-Window programming API in C

API :

A way for different software programs to talk to each other and work together :

• A software program wants to use the services provided by another program.
• The API acts as an intermediary, allowing the client to request specific actions or data from the other program.
• The server is the program that provides the functionality or data that the client want to access.

X Window System :

Its like a framework that helps your computer screen display graphics and handle input, such as mouse clicks and keyboard typing.

Functions :

• void *mlx_init( ) :

  • it sets up a connection to the X server allowing your program to communicate with it and perform graphical operations.
  • it allocates memory for a type t_xvar * variable which is a structure that represents internal variables and settings related to the X window system ; This structure typically holds information about the connection to the X server, as well as other configuration parameters needed for graphics operations.

  

  • it sets up default configurations for the graphics system, such as default window size, colors, and event handling behavior.
  • if initialization fails for any reason it provides appropriate error messages.

• int mlx_destroy_display(t_xvar *xvar) :

  • closes the connection to the X server for the display specified in the display structure and destroy all windows.

• void *mlx_new_window(t_xvar *xvar, int size_x, int size_y, char *title) :

  • it allocates a pointer of type t_win_list that will be returned earlier.
  • create a new window on the screen with a width and a height and title specified on the params.
  • returns that pointer that will represent that window.

• int mlx_loop(t_xvar *xvar) :

  • after initializing MinilibX and creating a new window, ‘mlx_loop’ is called to start the main event loop. Once ‘mlx_loop’ is called, the program will continuously process events and respond to user input until the program is terminated.
