QuestionHow do you get the file size for an open file? Pin
Member 41945938-Jan-13 3:29

I have the following code:

C++
FILE *fp = stdin;

if ((fp = fopen(argv[optind], "rb")) == NULL) {
     printf("Cannot open file %s\n", argv[optind]);
     return 2;
}


It executes correctly and the correct file is accessed.

I added the following to get the file size:

C++
SizeLow = GetFileSize(_fileno(fp), & SizeHigh);
if ((SizeLow == 0xFFFFFFFF) && ((Error = GetLastError()) != NO_ERROR)) {
     printf("Cannot read file size for %s, error %d\n", argv[optind], Error);
     help();
     return 2;
}
if (binary && (SizeHigh > 0x70000000)) {
    printf("File too big for Binary Mode\n");
    help();
    return 2;
}
__asm {
          mov   eax,SizeLow
          mov   edx,SizeHigh
          cmp   binary,TRUE
          jnz   Bytes
          shld  edx,eax,3
          shl   eax,3
      Bytes:
          mov   DWORD PTR totalc,eax
          mov   DWORD PTR totalc+4,edx
      }


When I execute I get the following:

C++
ent.exe f:\tst1.tst  >ent1.txt
Cannot read file size for f:\tst1.tst, error 6


What am I doing wrong with the the GetFileSize call?

In case you are wondering, this is a modification to John Walker's ENT to speed up execution for huge files.
