The meaning of the codes is approximately 491539Srgrimes * as follows: 501539Srgrimes * 511539Srgrimes * EX_USAGE -- The command was used incorrectly, e.g., with 521539Srgrimes * the wrong number of arguments, a bad flag, a bad 531539Srgrimes * syntax in a parameter, or whatever. 541539Srgrimes * EX_DATAERR -- The input data was incorrect in some way. 551539Srgrimes * This should only be used for user's data & not 561539Srgrimes * system files. 571539Srgrimes * EX_NOINPUT -- An input file (not a system file) did not 581539Srgrimes * exist or was not readable. This could also include 591539Srgrimes * errors like "No message" to a mailer (if it cared 601539Srgrimes * to catch it). 611539Srgrimes * EX_NOUSER -- The user specified did not exist. This might 621539Srgrimes * be used for mail addresses or remote logins. 631539Srgrimes * EX_NOHOST -- The host specified did not exist. This is used 641539Srgrimes * in mail addresses or network requests. 651539Srgrimes * EX_UNAVAILABLE -- A service is unavailable. This can occur 661539Srgrimes * if a support program or file does not exist. This 671539Srgrimes * can also be used as a catchall message when something 681539Srgrimes * you wanted to do doesn't work, but you don't know 691539Srgrimes * why. 701539Srgrimes * EX_SOFTWARE -- An internal software error has been detected. 711539Srgrimes * This should be limited to non-operating system related 721539Srgrimes * errors as possible. 731539Srgrimes * EX_OSERR -- An operating system error has been detected. 741539Srgrimes * This is intended to be used for such things as "cannot 751539Srgrimes * fork", "cannot create pipe", or the like. It includes 761539Srgrimes * things like getuid returning a user that does not 771539Srgrimes * exist in the passwd file. 781539Srgrimes * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 791539Srgrimes * etc.) does not exist, cannot be opened, or has some 801539Srgrimes * sort of error (e.g., syntax error). 811539Srgrimes * EX_CANTCREAT -- A (user specified) output file cannot be 821539Srgrimes * created. 831539Srgrimes * EX_IOERR -- An error occurred while doing I/O on some file. 841539Srgrimes * EX_TEMPFAIL -- temporary failure, indicating something that 851539Srgrimes * is not really an error. In sendmail, this means 861539Srgrimes * that a mailer (e.g.) could not create a connection, 871539Srgrimes * and the request should be reattempted later. 881539Srgrimes * EX_PROTOCOL -- the remote system returned something that 891539Srgrimes * was "not possible" during a protocol exchange. 901539Srgrimes * EX_NOPERM -- You did not have sufficient permission to 911539Srgrimes * perform the operation. This is not intended for 921539Srgrimes * file system problems, which should use NOINPUT or 931539Srgrimes * CANTCREAT, but rather for higher level permissions. 941539Srgrimes */ 951539Srgrimes 961539Srgrimes#define EX_OK 0 /* successful termination */ 971539Srgrimes 981539Srgrimes#define EX__BASE 64 /* base value for error messages */ 991539Srgrimes 1001539Srgrimes#define EX_USAGE 64 /* command line usage error */ 1011539Srgrimes#define EX_DATAERR 65 /* data format error */ 1021539Srgrimes#define EX_NOINPUT 66 /* cannot open input */ 1031539Srgrimes#define EX_NOUSER 67 /* addressee unknown */ 1041539Srgrimes#define EX_NOHOST 68 /* host name unknown */ 1051539Srgrimes#define EX_UNAVAILABLE 69 /* service unavailable */ 1061539Srgrimes#define EX_SOFTWARE 70 /* internal software error */ 1071539Srgrimes#define EX_OSERR 71 /* system error (e.g., can't fork) */ 1081539Srgrimes#define EX_OSFILE 72 /* critical OS file missing */ 1091539Srgrimes#define EX_CANTCREAT 73 /* can't create (user) output file */ 1101539Srgrimes#define EX_IOERR 74 /* input/output error */ 1111539Srgrimes#define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 1121539Srgrimes#define EX_PROTOCOL 76 /* remote error in protocol */ 1131539Srgrimes#define EX_NOPERM 77 /* permission denied */ 1141539Srgrimes#define EX_CONFIG 78 /* configuration error */ 1151539Srgrimes 1161539Srgrimes#define EX__MAX 78 /* maximum listed value */ 1171539Srgrimes 1181539Srgrimes#endif /* !_SYSEXITS_H_ */ 119
