OpenGL的土壤质地

Question

以下是错误消息我从VS2010 recieving： 0000005：访问冲突写入位置0x00000014

在0x77358dc9在AzimuthalEqui.e​​xe未处理的异常。

的码产生该错误的行是：

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

输入此功能之前：

texture_filename = “数据/ texture.jpg”

SOIL_LOAD_AUTO（= 0 ）

SOIL_CREATE_NEW_ID（= 0）

SOIL_flags = 16（= SOIL_FLAG_INVERT_Y）

的问题是，当我包括文件我已经写来解析在文本一些信息文件中产生错误，否则纹理加载并显示。这个概率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。 这里是功能，当添加到我的项目，使发生错误：

[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); 
} 

它是与打开文件进行读取...如果我注释掉这些行的纹理加载正确：

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

这是我缩减的代码（我不认为这是问题，但以防万一）。 [有可能是我的全部代码一些remanants]：

包括在我的项目，而不是固定的问题的.lib文件的.c文件。
