怎样编程把屏幕图像保存到24位位图?

int CBmpView::SaveBmpToFile(const char *filename, BITMAPINFO *info, UINT *bits)
{
FILE* fp;
UINT size, //Size of file
infosize, //Size of bitmap info
bitsize; //Size of bitmap pixels
BITMAPFILEHEADER header;
if((fp = fopen(filename,"wb")) == NULL)
return -1;
if(info->bmiHeader.biSizeImage == 0)
bitsize = (info->bmiHeader.biWidth *
info->bmiHeader.biBitCount+7)/8*
abs(info->bmiHeader.biHeight);
else
bitsize = info->bmiHeader.biSizeImage;

infosize = sizeof(BITMAPINFO);
size = sizeof(BITMAPFILEHEADER)+infosize+bitsize;

header.bfType = 'MB';
header.bfSize = size;
header.bfReserved1 = 0;
header.bfReserved2 = 0;
header.bfOffBits = sizeof(BITMAPFILEHEADER)+infosize;

if(fwrite(&header,1,sizeof(BITMAPFILEHEADER),fp) <
sizeof(BITMAPFILEHEADER))
{
fclose(fp);
return -1;
}

if(fwrite(info,1,infosize,fp) < infosize)
{
fclose(fp);
return -1;
}

if(fwrite(bits,1,bitsize,fp) < bitsize)
{
fclose(fp);
return -1;
}

fclose(fp);
return 1;
}
