Re: [Dev-C++] random access file updating

[Vassili <v.v...@bt...>]

I usually make a copy of the file, some of the modes create a new file =
that overwrites the stored file, copy the contents to the new file.
Don't forget, once you've read a record from the file that the file =
pointer has moved to the end of the record, so move it back one record =
to overwrite it, something like:

fseek(stream, (-1 * SIZE_OF_RECORD), SEEK_CUR)

If the stream is not a pointer use the address of character '&'.
The -1 means "go backwards once".
SEEK_CUR means from current position.

  hello all,

  I have an assignment due for a class in C programming.  we are working =
on random access files.  I have been able to write the code to add =
records and search the file, but I'm having trouble with updating the =
file.  Any hits on how to write over a record in a random access file??  =
