Checkin without working copy

[Stefano Righi <St...@ami.com>]

If there was a way to copy new versions of files into the repository without needing a working copy?
I am adding subversion support to a C application using svn client library.
Using WC has the disadvantage of checking out not only single files but entire directories. There is also a big overhead for creating the working copy's directory structure.
Is there any example available?
I would prefer to use the client library instead of the RA library.
