SDL_CreateWindow函数：

用此函数在指定的位置，指定窗口大小，以及相应标志来创建窗口。

定义：

SDL_Window* SDL_CreateWindow(const char* title,                             int         x,                             int         y,                             int         w,                             int         h,                             Uint32      flags)

例子：

#include "SDL.h"#include 
   
    int main(int argc, char* argv[]) {    SDL_Window *window;                    // Declare a pointer    SDL_Init(SDL_INIT_VIDEO);              // Initialize SDL2    // Create an application window with the following settings:    window = SDL_CreateWindow(        "An SDL2 window",                  // window title        SDL_WINDOWPOS_UNDEFINED,           // initial x position        SDL_WINDOWPOS_UNDEFINED,           // initial y position        640,                               // width, in pixels        480,                               // height, in pixels        SDL_WINDOW_OPENGL                  // flags - see below    );    // Check that the window was successfully created    if (window == NULL) {        // In the case that the window could not be made...        printf("Could not create window: %s\n", SDL_GetError());        return 1;    }    // The window is open: could enter program loop here (see SDL_PollEvent())    SDL_Delay(3000);  // Pause execution for 3000 milliseconds, for example    // Close and destroy the window    SDL_DestroyWindow(window);    // Clean up    SDL_Quit();    return 0;}
