• File src/OFWideCString.m — part of check-in [b597d49f43] at 2008-10-08 23:15:26 on branch trunk — Multiple changes, see details.

  * OFObject getMem: renamd to getMemWithSize:.
  * OFString compare: renamed to compareTo:.
  * Exceptions don't throw itself anymore.
  * Exceptions include an error string now.
  * Exceptions now got raise and string.
  * New methods for OFFile:
  * changeModeOfFile:toMode:
  * changeOwnerOfFile:toOwner:andGroup:
  * delete:
  * link:to:
  * symlink:to:
  * OFFile isEndOfFile renamd to atEndOfFile
  * OFNotImplementedExeception newWithObject:andMethod renamed to
  newWithObject:andSelector:.
  * Tests updated accordingly.
  * TODO list added. (user: js, size: 1311) [annotate] [blame] [check-ins using]
