[jira] [Commented] (IO-305) New copy() method in IOUtils that takes additional offset, length and buffersize arguments

["Sebb (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IO-305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13224225#comment-13224225 ] 

Sebb commented on IO-305:
-------------------------

Should use long for the offset and length.

It would be useful to return the number of bytes actually copied, as per the copyLarge methods.
