c - 土壤质地

以下是我从VS2010接收到的错误消息：
AzimuthalEqui.exe中0x77358dc9处未处理的异常：
0xC0000005:访问冲突写入位置0x00000014。
生成此错误的代码行是：

texture[1] = SOIL_load_OGL_texture
    (
        texture_filename,
        SOIL_LOAD_AUTO,
        SOIL_CREATE_NEW_ID, // create ID automatically
        SOIL_flags
    );

在进入此功能之前：
texture_filename=“Data/texture.jpg”
土壤荷载自动（=0）
土壤创建新ID（=0）
土壤标志=16（=土壤标志反向）
问题是，当我在文本文件中包含一个用于解析某些信息的文件时，将生成一个错误，否则将加载并显示纹理。prob很可能是由一个函数引起的，因为当这个特定的函数被移除时，代码将加载并显示纹理。
下面是添加到我的项目中时出错的函数：

[CODE]
void get_user_points(double *lats, double *longs){

    char buffer[BUFFSIZE_PARSE];
    char *p_buff = buffer;
    FILE *fp;
    const char *filename = "Points.txt";
    double temp;
    double *tmp_p = &temp;


    fp = fopen(filename,"r+");
    if (fp == NULL)
    {
        sprintf(buffer, "Can't Find File: %s", filename);
        MessageBoxA(NULL, buffer, "ERROR", MB_OK|MB_ICONEXCLAMATION);
        exit(0);
    }

    fgets(buffer, BUFFSIZE_PARSE, fp);

    while (*(p_buff+1) != '\0'){

        p_buff = get_next_letter(p_buff);

        switch (tolower(*p_buff)){
            case 'n':
                putchar(*p_buff);
                p_buff++;
                p_buff=get_next_double(lats, p_buff);
                printf(" = %f\n", *lats);
                break;
            case 's':
                ...
                ...
        }
    }
    putchar('\n');
    fclose(fp);
}

它与打开文件进行读取有关。。。如果我注释掉这些行，纹理将正确加载：

//fpr = fopen(filename2,"rb");
...
...
...
//fclose(fpr);

这是我的简化代码（我不认为这是问题，但只是以防万一）。[可能还有一些还押候审者我的全部密码]：

最佳答案

在我的项目中包含.c文件而不是.lib文件解决了这个问题。
