-DESCRIPTION
- logmsg prints error, warning, or info/logging messages to stderr and
- potentially terminates the calling program, depending on the class
- given. who is the name of the program, ecode is an error code, class
- determines the behavior upon call and msg is the logging message. Read
- "error.h" to learn more about related constants.
-
-ECODE
- ecode is the error code and subject to be displayed in the log file and
- potentially used upon exit if the class equals ERROR, FATAL, or DROP.
-
- To avoid conflicts with syscall error codes, appplication defined error
- codes should be negative. The values -15, -100 and -111 are reserved
- for backward compatibility.
-
-CLASS
- The class parameter indicates how the application handles exceptions
- and displays the log message.
-
- o LOG, INFO, ALERT, WARN - display message and continue operation
-
- o DROP - display warning message and continue while returning to the
- calling program
-
- o USAGE, SYNTAX, FATAL, ERROR - display error message and exit appli‐
- cation with error code
-
- INFO, ALERT, WARN, DROP, USAGE, and FATAL as well as ERROR display the
- respective class string like warning: in the log message, while LOG
- shows the log message only.
-
- The class FATAL should be used for system error codes only, rather ER‐
- ROR and WARN shall be set in conjunction with an application er‐
- ror/warning.
-
-MESSAGE
- If the custom message msg is given, it will be printed additionally.
-
- Dan Bernstein used sets of strerr_dieY*() and strerr_warnY() messages
- which explicitely determine the message and behavior class. Other
- classes were occasionally defined on demand, such als usage().
-
- Kai Peter introduced the errmsg facility in his qlibs including a sys‐
- log compliant severity as second parameter.
-
-EXAMPLES
- The macro definitions uses w for the calling program, e for error
- code, c for class, and m for message.
-
- #include "logmsg.h"
- #define WHO "my_prog"
-
- err_sys(WHO,errno);
- err_sys_plus(WHO,-111,"additional message");
-
- err_tmp("",-100);
- err_tmp_plus("",errno,"additional message");
-
- log_who(WHO,"message");
-
- log_anon() is like log_who() but doesn't print the caller name.
-
- An user defined message s can be build from multiple arguments by using
- the B (build) macro:
-
- err_sys_plus((errno),B("unable to run: ",*argv));
