function pointers alone. The utility.library/CallHookPkt mechanism is no longer required. - Moved the entire lseek() code relevant for files into the hook function. - Simplified the close() function which now just calls into the hook code to perform whatever is necessary. The hook code is responsible for cleaning up after aliases, etc. This change in turn made it possible to greatly simplify the hook code for buffered files which now bypasses close/read/write/lseek and directly invokes the hook code for unbuffered files. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14835 87f5fb63-7c3d-0410-a384-fd976d0f7a62
