The meaning of the codes is approximately 30** as follows: 31** 32** EX_USAGE -- The command was used incorrectly, e.g., with 33** the wrong number of arguments, a bad flag, a bad 34** syntax in a parameter, or whatever. 35** EX_DATAERR -- The input data was incorrect in some way. 36** This should only be used for user's data & not 37** system files. 38** EX_NOINPUT -- An input file (not a system file) did not 39** exist or was not readable. This could also include 40** errors like "No message" to a mailer (if it cared 41** to catch it). 42** EX_NOUSER -- The user specified did not exist. This might 43** be used for mail addresses or remote logins. 44** EX_NOHOST -- The host specified did not exist. This is used 45** in mail addresses or network requests. 46** EX_UNAVAILABLE -- A service is unavailable. This can occur 47** if a support program or file does not exist. This 48** can also be used as a catchall message when something 49** you wanted to do doesn't work, but you don't know 50** why. 51** EX_SOFTWARE -- An internal software error has been detected. 52** This should be limited to non-operating system related 53** errors as possible. 54** EX_OSERR -- An operating system error has been detected. 55** This is intended to be used for such things as "cannot 56** fork", "cannot create pipe", or the like. It includes 57** things like getuid returning a user that does not 58** exist in the passwd file. 59** EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 60** etc.) does not exist, cannot be opened, or has some 61** sort of error (e.g., syntax error). 62** EX_CANTCREAT -- A (user specified) output file cannot be 63** created. 64** EX_IOERR -- An error occurred while doing I/O on some file. 65** EX_TEMPFAIL -- temporary failure, indicating something that 66** is not really an error. In sendmail, this means 67** that a mailer (e.g.) could not create a connection, 68** and the request should be reattempted later. 69** EX_PROTOCOL -- the remote system returned something that 70** was "not possible" during a protocol exchange. 71** EX_NOPERM -- You did not have sufficient permission to 72** perform the operation. This is not intended for 73** file system problems, which should use NOINPUT or 74** CANTCREAT, but rather for higher level permissions. 75*/ 76 77# if SM_CONF_SYSEXITS_H 78# include <sysexits.h> 79# else /* SM_CONF_SYSEXITS_H */ 80 81# define EX_OK 0 /* successful termination */ 82 83# define EX__BASE 64 /* base value for error messages */ 84 85# define EX_USAGE 64 /* command line usage error */ 86# define EX_DATAERR 65 /* data format error */ 87# define EX_NOINPUT 66 /* cannot open input */ 88# define EX_NOUSER 67 /* addressee unknown */ 89# define EX_NOHOST 68 /* host name unknown */ 90# define EX_UNAVAILABLE 69 /* service unavailable */ 91# define EX_SOFTWARE 70 /* internal software error */ 92# define EX_OSERR 71 /* system error (e.g., can't fork) */ 93# define EX_OSFILE 72 /* critical OS file missing */ 94# define EX_CANTCREAT 73 /* can't create (user) output file */ 95# define EX_IOERR 74 /* input/output error */ 96# define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 97# define EX_PROTOCOL 76 /* remote error in protocol */ 98# define EX_NOPERM 77 /* permission denied */ 99# define EX_CONFIG 78 /* configuration error */ 100 101# define EX__MAX 78 /* maximum listed value */ 102 103# endif /* SM_CONF_SYSEXITS_H */ 104 105extern char *sm_strexit __P((int)); 106extern char *sm_sysexitmsg __P((int)); 107extern char *sm_sysexmsg __P((int)); 108 109#endif /* !
