- * $Log: Concat.c,v $
- * Revision 37.12 93/03/30 12:58:19 Torsten
- * Added explicit check for read errors to fastcat().
- *
- * Revision 37.11 93/03/26 11:11:53 Torsten
- * Now uses another copying algorithm if the VISIBLE switch is not
- * specified and the destination is not a virtual terminal.
- * An ad hoc test showed a twentyfold speed increase.
- * Removed the QUIET switch as it wasn't used anyway ;-).
- *
- * Revision 37.10 93/03/01 12:40:46 Torsten
- * Changed all occurrences of "struct DosBase *" to "struct DosLibrary *"
- *
- * Revision 37.9 93/02/24 00:21:33 Torsten
- * Bug fix: called FreeArgs() too soon.
- *
- * Revision 37.8 93/02/23 22:40:36 Torsten
- * Now it only stores filenames in a list if the sort switch is given.
- * The entrypoint function has been restructured a bit to get rid of
- * the gotos.
- *
- * Revision 37.7 93/02/22 18:15:42 Torsten
- * Changed to be linked with the support library
- *
- * Revision 37.6 93/02/19 18:00:14 Torsten
- * Rewritten almost from scratch.
- * UNBUF switch removed.
- *
- * Revision 37.5 93/02/18 15:24:25 Torsten
- * Removed explicit utility.library/Stricmp() pragma and prototype.
- * Replaced AllocMem()/FreeMem() pair with AllocVec()/FreeVec().
- *
- * Revision 37.4 93/02/11 22:47:48 Torsten
- * Source reformatted with GNU indent.
- * exec.library/SetSignal() replaced by dos.library/CheckSignal().
- *
- * Revision 37.3 93/02/07 11:41:37 Torsten
- * Updated the copyright tag.
- *
- * Revision 37.2 93/02/05 11:36:10 Torsten
- * checked in with -k by Torsten at 93.02.05.11.36.10.
