保存一个文件并创建对应的目录文件夹

void SaveFile( const char* szFileName, const char* szBuffer, unsigned int nSize )

{// 循环创建目录
if(strncmp(&szFileName[i], "/", 1) == 0)

strncpy(szName, szFileName, i);
_mkdir(szName);
}
}
fp = fopen(szFileName, "wb");
if(!fp)
return;
}
fwrite(szBuffer, nSize, 1, fp);
fclose(fp);
}
void Main()

// 将一个文件读入内存
