c++ - 魔鬼 iluErrorString() 导致访问冲突

Question

请看我第一天VC++的成果。它包含一个我知道的错误。我的问题是 devil 出现了错误，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;
}

它发出错误 1285，表示它不理解:

ilLoadL(IL_PNG, Lump, fileSize);

这个我是知道的。问题出在这里:

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

这会导致访问冲突，我不知道为什么？

如果您没有像初始化 IL 那样初始化 ILU，就会出现此问题:

iluInit();
