The meaning of the codes is approximately 32** as follows: 33** 34** EX_USAGE -- The command was used incorrectly, e.g., with 35** the wrong number of arguments, a bad flag, a bad 36** syntax in a parameter, or whatever. 37** EX_DATAERR -- The input data was incorrect in some way. 38** This should only be used for user's data & not 39** system files. 40** EX_NOINPUT -- An input file (not a system file) did not 41** exist or was not readable. This could also include 42** errors like "No message" to a mailer (if it cared 43** to catch it). 44** EX_NOUSER -- The user specified did not exist. This might 45** be used for mail addresses or remote logins. 46** EX_NOHOST -- The host specified did not exist. This is used 47** in mail addresses or network requests. 48** EX_UNAVAILABLE -- A service is unavailable. This can occur 49** if a support program or file does not exist. This 50** can also be used as a catchall message when something 51** you wanted to do doesn't work, but you don't know 52** why. 53** EX_SOFTWARE -- An internal software error has been detected. 54** This should be limited to non-operating system related 55** errors as possible. 56** EX_OSERR -- An operating system error has been detected. 57** This is intended to be used for such things as "cannot 58** fork", "cannot create pipe", or the like. It includes 59** things like getuid returning a user that does not 60** exist in the passwd file. 61** EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 62** etc.) does not exist, cannot be opened, or has some 63** sort of error (e.g., syntax error). 64** EX_CANTCREAT -- A (user specified) output file cannot be 65** created. 66** EX_IOERR -- An error occurred while doing I/O on some file. 67** EX_TEMPFAIL -- temporary failure, indicating something that 68** is not really an error. In sendmail, this means 69** that a mailer (e.g.) could not create a connection, 70** and the request should be reattempted later. 71** EX_PROTOCOL -- the remote system returned something that 72** was "not possible" during a protocol exchange. 73** EX_NOPERM -- You did not have sufficient permission to 74** perform the operation. This is not intended for 75** file system problems, which should use NOINPUT or 76** CANTCREAT, but rather for higher level permissions. 77*/ 78 79# if SM_CONF_SYSEXITS_H 80# include <sysexits.h> 81# else /* SM_CONF_SYSEXITS_H */ 82 83# define EX_OK 0 /* successful termination */ 84 85# define EX__BASE 64 /* base value for error messages */ 86 87# define EX_USAGE 64 /* command line usage error */ 88# define EX_DATAERR 65 /* data format error */ 89# define EX_NOINPUT 66 /* cannot open input */ 90# define EX_NOUSER 67 /* addressee unknown */ 91# define EX_NOHOST 68 /* host name unknown */ 92# define EX_UNAVAILABLE 69 /* service unavailable */ 93# define EX_SOFTWARE 70 /* internal software error */ 94# define EX_OSERR 71 /* system error (e.g., can't fork) */ 95# define EX_OSFILE 72 /* critical OS file missing */ 96# define EX_CANTCREAT 73 /* can't create (user) output file */ 97# define EX_IOERR 74 /* input/output error */ 98# define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 99# define EX_PROTOCOL 76 /* remote error in protocol */ 100# define EX_NOPERM 77 /* permission denied */ 101# define EX_CONFIG 78 /* configuration error */ 102 103# define EX__MAX 78 /* maximum listed value */ 104 105# endif /* SM_CONF_SYSEXITS_H */ 106 107extern char *sm_strexit __P((int)); 108extern char *sm_sysexitmsg __P((int)); 109extern char *sm_sysexmsg __P((int)); 110 111#endif /* !
