/* * 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 check is done by trying to open bsdsocket * library. * * 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: -a Does not do online check * -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 * int amitcp flag - dont check for online * 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 4.1 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 * * */ #include #include #include #include #include #include #include #include #define SPOOLDIR "AmiTCP:Usr/Spool/News" #define MAX_DEL 16 void copyfile( FILE *, FILE * );
