我只是试图用一个简单的渲染器创建一个简单的SDL2窗口。当我调试它时,它可以正常运行,内存仍然正常。但是,当我最小化它时,按下最小化按钮,然后内存突然增加,仅当我重新打开该窗口时,内存才恢复正常。
代码:
#include <SDL.h>
#include <SDL_image.h>
int main(int argc, char* args[]) {
SDL_Window* gWindow;
SDL_Renderer* gRenderer;
SDL_Texture* gTexture;
SDL_Surface* temp;
//Init
SDL_Init(SDL_INIT_VIDEO);
gWindow = SDL_CreateWindow("Test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 1366, 768, SDL_WINDOW_SHOWN);
gRenderer = SDL_CreateRenderer(gWindow, -1, SDL_RENDERER_ACCELERATED);
IMG_Init(IMG_INIT_PNG);
//loading medias
temp = IMG_Load("assets/sprites/700.png");
gTexture = SDL_CreateTextureFromSurface(gRenderer, temp);
SDL_FreeSurface(temp);
//The main loop
bool quit = false;
SDL_Event e;
while (!quit)
{
while (SDL_PollEvent(&e) != 0)
{
if (e.type == SDL_QUIT)
{
quit = true;
}
}
SDL_RenderClear(gRenderer);
SDL_RenderCopy(gRenderer, gTexture, NULL, NULL);
SDL_RenderPresent(gRenderer);
}
//Destroy things
SDL_DestroyTexture(gTexture);
gTexture = NULL;
SDL_DestroyRenderer(gRenderer);
SDL_DestroyWindow(gWindow);
gWindow = NULL;
gRenderer = NULL;
IMG_Quit();
SDL_Quit();
return 0;
}
我只是运行您的代码并进行了编译。看起来不错。但是,您确实提到过,当最小化夯表增加的程序时,您能够执行此重复操作多长时间才崩溃?甚至崩溃吗?这可能是正常行为。如果您的程序崩溃,则可能是内存泄漏,这可能表明您忘记了取消分配其他指向内存对象/变量的指针。
