TELL(DOS)                XENIX System V                 TELL(DOS)



     Name
          tell - Gets the current position of the file pointer.

     Syntax
          #include <io.h>

          long tell (handle);
          int handle;

     Description
          The tell function gets the current position of the file
          pointer (if any) associated with handle.  The position is
          expressed as the number of bytes from the beginning of the
          file.

     Return Value
          tell returns the current position.  A return value of -1L
          indicates an error, and errno is set to EBADF to indicate an
          invalid file handle argument.  On devices incapable of
          seeking (such as terminals and printers), the return value
          is undefined.

     See Also
          fseek(S), lseek(S)

     Example
          #include <io.h> #include <stdio.h> #include <fcntl.h>

          int fh; long position;

          fh = open ("data",ORDONLY);      .       .       .  position
          = tell (fh);    /* remember current position */      .
               .       .  lseek (fh, position, 0); /* seek to previous
          position */

     Notes
          This call must be compiled with the -dos flag.
