Question

请看看我的第一天VC ++的结果。它包含我所知道的错误。我的问题是devil会出现错误，但尝试使用iluErrorString（）将此错误解码为字符串会导致访问冲突......

#pragma comment(lib, "ILU.lib")
#pragma comment(lib, "ILUT.lib")

#include <iostream>
#include <conio.h>
#include <stdio.h>

#include <IL/il.h>
#include <IL/ilu.h>
#include <IL/ilut.h>

using namespace std;

int main(){
FILE *myFile;
ILuint fileSize;
ILubyte *Lump;

ilInit();

ILuint ImageName; // The image name to return.
ilGenImages(1, &ImageName); // Grab a new image name.

ilBindImage(ImageName); //bind the image

myFile = fopen("C:/Documents and Settings/Bartjan/Desktop/c++ meuq/test/Debug/image.png", "r"); //open the file for reading
if (myFile != NULL){
    fseek(myFile, 0, SEEK_END); //get file size
    fileSize = ftell(myFile);

    Lump = (ILubyte*)malloc(fileSize); //allocate mem
    fseek(myFile, 0, SEEK_SET); //set the file pointer
    fread(Lump, 1, fileSize, myFile); //read the entire file into mem

    fclose(myFile);

    ilLoadL(IL_PNG, Lump, fileSize);
    free(Lump);
}

ilDeleteImages(1, &ImageName); //delete the image

ILenum error;
while ((error = ilGetError()) != IL_NO_ERROR) {
    cout << error << ": " << iluErrorString(error);
}

_getch();
return 0;
}

它咳出一个错误1285意味着它不理解这个：

ilLoadL(IL_PNG, Lump, fileSize);

我知道这一点。问题出在这里：

cout << error << ": " << iluErrorString(error);

这导致访问违规，我无法弄清楚原因？

Answer 1

如果您没有像IL那样初始化ILU，则会出现此问题：

iluInit();

Answer 2

这是因为iluErrorString总是和ilGetString一样返回0。

Devil iluErrorString（）导致访问冲突
