* libbe_build: Where possible we directly use the actual Haiku headers and sources, now. In the headers/build headers we just include the respective Haiku headers as needed. That still allows overrides where necessary. The intention is to make it easier to keep the build stuff in sync. * Fixed a few printf() format and signed/unsigned comparison warnings. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42179 a95241bf-73f2-0310-859d-f6bbb57e9c96

\class BFile
|
|
\brief BFile is a wrapper class for common operations on files providing
|
|
access to the file's content data and its attributes.
|
|
|
|
A BFile represents a file in some file system. It implements the
|
|
BPositionIO interface and thus the methods to read from and write to the
|
|
file, and is derived of BNode to provide access to the file's attributes.
