* Program postnews
* Programmer N.d'Alterio
* Date 06/07/95
*
* Synopsis: This program spools an news article ready for posting at
* some later time. If currently online then sendnews is
* called and the article will be sent off immediately.
* The online by checking env var ONLINE
*
* This is a heavily modified version of postnews by
* James Burton from his postnewsspool package. This fixes
* a number of bugs such as the leaving of locks, hanging
* for a long time while waiting to see if it is online.
* In addition the program has been very much streamlined
* there are no longer the command line options -X, -R as
* these seemd to have no use. Also gone are the arg### and
* ref### files it produced which seemed to be useless.
*
* For tin users the program has the command line option
* -f the add a From: user@somewhere to the header.
*
* This program has the paths for my setup compiled into
* it as defaults to use different paths and files there
* is an env variable PNS_SPOOLDIR which is the full directory
* name for the spool dir with no trailing '/'.
*
* The program expects to have the companion program sendnews
* in AmiTCP:bin/sendnews which in turn needs to have the
* NNTP posting program as AmiTCP:bin/NNTPPost.
*
* Command Line Arguments: -n Does not send if online
* -R Specifies header filename
* -x File to delete if successful
* -f Adds a From: someone@ line to header
* -h Prints some help info
* filename The article file to post
* if omitted will take from STDIN
*
* Inputs: article Should contain a full header
* or
* header article header
* body article body
*
* Outputs: spooldir/msg.### The spooled message
*
* Variables: int i general loop var
* int exit_code return code for prog
* BPTR lock lock on spooldir
* char *Buffer string to build filenames
* FILE *msg_fptr file to contain spooled article
* FILE *body_fptr file containing article body
* FILE *head_fptr fiel containing article header
* int no_post flag - don't try to send
* char *from Pointer to from string
* char *body_fname Pointer to body filename
* char *head_fname Pointer to header filename
* int status delete status flag
* int num_del Number of files to be deleted
* char *Todelete[] Buffer containing names of files to delete
*
* Functions: copyfile copies article to spooldir
* NextArg checks for existance of next argument
*
* $VER: postnews.c 2.1 (07.08.95) $
* $Log: postnews.c $
* Revision 4.2 1996/04/20 13:31:31 nagd
* new online check via ONLINE env var
* remove DOS library open/close code
* removed arg -a
* sendnews now only needs to be on path
*
* Revision 4.1 1995/12/19 17:47:57 nagd
* addded options -R, -x, -a new online check
*
*
* Revision 3.3 1995/09/30 21:25:18 daltern
* new command line option -n
*
* Revision 3.2 1995/09/30 21:17:20 daltern
* Added new env var PNS_OFFLINE
* improved error handling
*
* Revision 3.1 1995/09/10 16:41:41 daltern
* Removed need for seq file to comply with v3.1 of sendnews
* spooled messages now have name of form msg.##########
* where ###### is the long date returned by time()
*
*
* Revision 1.2 1995/08/27 21:49:10 daltern
* Added env vars for path options
* fixed a bug where a file was left open
*
* Revision 1.1 1995/08/07 14:17:55 daltern
* Initial revision
