Cosmetics. * - 0.10a (27/08/98) : Integration of the parser module into the *   main sms_serv program. Merged server.h into this file. *   Added code to prevent double inclusion. Cosmetics. * - 0.11a (01/09/98) : Increased BUFFSIZE from 200 to 400. * - 0.12a (27/09/98) : Added MINIBUFF define. * - 1.13a (19/10/98) : Added GSMDEVFILE define and function *   definitions for gsmdevices.c. Changed 'struct modem_def' *   to 'struct gsms_def' and added fields. * ++++ Switched to Beta ++++ * - 0.14b (23/10/98) : Added 'user' member in 'symbols' struct *   and defined MAXUIDLEN. * - 0.15b (22/11/98) : Added MBCHKINTERVAL define. * - 0.16b (13/12/98) : Added member "owner" to struct gsms_def. * - 0.17b (06/02/99) : Added support for access control. *   Contributed by Philipp Klaus <pklaus@access.ch>. * - 0.18b (11/02/99) : Start rewriting of ACL support. * - 0.19b (14/02/99) : Declared public functions for new ACL *   implementation. * - 0.20b (28/06/99) : Added struct mbox_item to be used by *   mbcheck() and friends. * - 0.21b (29/06/99) : Moved 3 functions to stuff.c and made *   them public. * - 0.22b (03/07/99) : Added public definition for trim(). * - 0.23b (11/07/99) : Added mailbox files definitions. * - 0.24b (17/08/99) : Added checkpoint file definition for *   interaction with the SMS to mail gateway. * - 0.25b (18/08/99) : Published mailgws_death(). * - 0.26b (20/08/99) : Adapted structure after splitting *   stuff.c. Mostly cosmetic. * - 0.27b (25/08/99) : Added MAXRETRIES define, as well as *   version tracking for sms2mailgw. * - 0.28b (28/09/99) : Created struct email_msg and inbox_line, *   and exported mailbox_run(). Defined DEFAULTDOMAIN. * - 0.29b (17/10/99) : Added FIELD_HEADERS definition. * - 0.30b (20/10/99) : Added GWUSER definition. * - 0.31b (21/10/99) : Added MAILHOST definition. Moved tellsock() *   definition to stuff.c. * - 0.32b (09/11/99) : Added nicedate() declaration (exported by *   stuff.c). * - 0.33b (02/12/99) : Changed DEFAULTSMSC to a catch-all *   "default" value in order to improve its handling. See *   send_sms() in server.y. Added public export of empty_acl_list() *   to accessctrl.c (for "aclist" command). * - 0.34b (29/02/00) : Changed struct email_msg to replace recepients *   fields with linked lists for easier handling by send_mail(). *========================================================*/#ifndef _SMS_SERV_H#define _SMS_SERV_H/* Program information */#define SMS_SERV_VERSION	"0.44b"#define SMS_SERV_DATE		"25/02/00"#define PROMPT			"SMS> "/* GSM devices */#define GSMDEVFILE		"/etc/gsmdevices"#define PINLEN			4#define PUKLEN			8#define MAXATTEMPTS		4        	/* 3 wrong PIN's + 1 PUK */#define CTRL_Z			"\x1A"		/* SM end marker *//* access control (INA) */#define ACCESSFILE		"/etc/gsmaccess"#define MAXACLS			10000		/* precaution */#define ACL_ALLOW		1#define ACL_DENY		2/* Buffer handling */#define BUFFSIZE		400#define MINIBUFF		80		/* for hostname, for inst. */#define BIGBUFF			1024/* SMS Messages-related */#define MAXPHNUMLEN		80		/* max length for phone num */#define MAXMSGLEN		160		/* max msg length for SMS */#define DEFAULTSMSC		"default"	/* device-level default */#define MAXUIDLEN		12		/* max length for sender ID *//* For incoming messages handling */#define MBCHKINTERVAL		3600		/* mailbox check interv.(sec)*/#define MBOX_FILE		"/var/spool/smslink/inbox"#define MBOX_LOCKF		"/var/spool/smslink/LCK..inbox"#define CHECKPOINTF		"/var/spool/smslink/checkpoint"/* For the SMS to Mail gateway */#define SMS_GW_VERSION		"0.07b"#define SMS_GW_DATE		"02/03/00"#define MAXRETRIES		5		/* max tries to lock inbox */#define MAILHOST		"localhost"	/* SMTP relay */#define DEFAULTDOMAIN		"."             /* set to override server's */#define GWUSER			"smsgw"		/* local user for mail deliv. */#define FIELD_HEADERS		"TCRBFS"        /* supported field headers *//* For the logging calls */#include <syslog.h>#define FACILITY		LOG_USER	/* default *//* Local socket options */#define MAXCLIENTCONN		5		/* max socket queue length */#define MAXCHILDPROC		5		/* max child processes *//* Semaphore-related parameters */#define MAXMODEMS		2		/* max supported modem devs */#define M_TIMEOUT		90		/* secs wait for free modem */#define W_STEP			5		/* secs to sleep *//* Modem-related parameters */#define MAXDEVLEN		40		/* max. device name length *//* Can be usefull */#define TRUE        1#define FALSE       0/*========================================================== * Structure Declarations *========================================================*/#include <unistd.h>                  /* for pid_t typedef */#include <netinet/in.h>            /* for struct acl_item *//* This  structure defines an outbound SMS message */struct symbols {  char *smsc;                           /* message center */  char *destgsm;                       /* destination gsm */  char *message;                          /* message text */  char *user;                    /* sender identification */};/* This structure stores an incoming message */struct mbox_item {  int msgid;                       /* used for SIM access */  char fromgsm[MAXPHNUMLEN + 1];     /* sender GSM number */  char date[9];                        /* format YYYYMMDD */  char time[10];                      /* format xxhyymzzs */  char text[MAXMSGLEN + 1];  struct mbox_item *next;  struct mbox_item *prev;};typedef struct mbox_list_header {  struct mbox_item *head;  struct mbox_item *tail;} mbox_list;/* This defines a gsm device instance */struct gsms_def {  int free;                                 /* bool value */  pid_t owner;                    /* pid of owner process */  char device[MAXDEVLEN + 1];              /* device name */  char PIN[PINLEN + 1];                       /* PIN code */  char PUK[PUKLEN + 1];                       /* PUK code */  char addr[MAXPHNUMLEN + 1];       /* SIM calling number */  char defsca[MAXPHNUMLEN + 1]; /* def.
