如何打开读取16位.raw文件Vc++（Wince平台）

Question

我正在尝试在 Wince 平台上使用 c++ (visual studio 2013) 读取 16 位 .raw 文件。但不确定 api 应该用于打开和读取操作。它似乎对图像文件的文件操作不同于 .txt 文件。请帮助我获取读取 16 位原始数据的示例代码。

注意：以下代码在 C 中运行良好，也可以在（但不是最佳的）c++ 中编译。

如果用 C 编码，则使用 fopen(,) is a good option, and the 2nd argument is key as it sets the function to perform several variations of opening a file, including binary reads. The following excerpt is one of several sections provided in the C Tutorial – Binary File I/O:

#include<stdio.h>

/* Our structure */
struct rec
{
    int x,y,z;
};

int main()
{
    int counter;
    FILE *ptr_myfile;
    struct rec my_record;

    ptr_myfile=fopen("test.bin","rb");//note the argument 'rb' for read binary
    if (!ptr_myfile)
    {
        printf("Unable to open file!");
        return 1;
    }
    for ( counter=1; counter <= 10; counter++)
    {
        fread(&my_record,sizeof(struct rec),1,ptr_myfile);
        printf("%d\n",my_record.x);
    }
    fclose(ptr_myfile);
    return 0;
}
