2000-01-24 bertrand <bertrand@helixcode.com> * camel/camel-seekable-stream.c: * camel/camel-seekable-stream.h: * camel/camel-simple-data-wrapper-stream.h: parent class is now CamelSeekableStream * camel/camel-stream-buffered-fs.h: idem * camel/camel-stream-buffered-fs.c: idem * camel/camel-stream-mem.h: idem * camel/camel-stream-mem.c: idem (_seek): change declaration * camel/camel-stream-fs.c: parent class is now CamelSeekableStream (_seek): change declaration * camel/camel-stream-fs.h: parent class is now CamelSeekableStream Major compatible change in the stream hierarchy. Removed the seek method from the general streams so that we can use them as "DataSources". svn path=/trunk/; revision=1622
