Hii
Using ftell() after fopen(..., "a") returns 0 even when the file open for
appending is not empty. AFAIK, it should return the size of the file.
Not a bug. POSIX allows this behavior, and Linux does it as well. POSIX
also allows BSD behavior of seeking to the end, although this is less
friendly to reading back a file opened with fopen(...,"a+"). So portable
programs can't expect either situation, and you MUST use fseek when
opening for append if you expect a particular position.
however writing will always take place at the end of the file.
"Opening a file with append mode (a as the first character in the mode
argument) shall cause all
subsequent writes to the file to be forced to the then current
end-of-file, regardless of intervening
calls to fseek( )."
