rsync - Jan 2006 - Checksum of a file

Hi all,

With reference to the mail subjected : IO Timeout Error in file less than 3 MB,
 thanks to Wayne Davison and Tony for having suggested the changes to be done.
 I have moved to rsync version 2.6.6 from the 2.4 series. 

As per my project requirement,  i need to know  the checksum of the file being
synced.
For this purpose i tried debugging the code. I understand that rsync breaks the
entire file
into blocks and calculates checksum for each block. 
>From the source code, i have come across a function
 void file_checksum(char *fname,char *sum,OFF_T size) where i understood that
checksum is calculated.

Is there a way where i can get the checksum of the entire file at once ?

Is what i understood about checksum right ?
Can anybody please help me in this issue ?
 

Thanks in Advance.
Regards,
Vijay Ram.C

The sender computes the full-file checksum at the end of the transfer
and sends it to the receiver.  This code is in match.c (look for the
sum_end(file_sum) call).  The receiver is also computing the checksum
(so that it can compare it to check the transfer), and that code is in
receiver.c (look for the sum_end(file_sum1) call).  You can output the
checksum from either spot in the code:  use rprint(INFO, ...) if you
want to output the checksum to stdout, for instance.
