从一个图片读数据，由这个数据来填充新建图片文件

FILE * file1;
char * szTxt;
int nLen;
file1 = fopen("f:\\temp\\test.bmp", "rb");
fseek(file1, 0, SEEK_END);
nLen = ftell(file1);//nlen文件长度
fseek(file1, 0, SEEK_SET);
szTxt = (char *)malloc(nLen);
nLen = fread(szTxt, 1, nLen, file1);
fclose(file1);

FILE * file2;
file2 = fopen("f:\\temp\\1.bmp", "wb");
fseek(file2, 0, SEEK_SET);
fwrite(szTxt, 1, nLen, file2);

fclose(file2);

头文件什么的，自己加就是了(●'◡'●)
