fmtmsg.h — message display structures

Synopsis

#include <fmtmsg.h>

Description

The <fmtmsg.h> header shall define the following symbolic constants:

MM_HARD
Source of the condition is hardware.
MM_SOFT
Source of the condition is software.
MM_FIRM
Source of the condition is firmware.
MM_APPL
Condition detected by application.
MM_UTIL
Condition detected by utility.
MM_OPSYS
Condition detected by operating system.
MM_RECOVER
Recoverable error.
MM_NRECOV
Non-recoverable error.
MM_HALT
Error causing application to halt.
MM_ERROR
Application has encountered a non-fatal fault.
MM_WARNING
Application has detected unusual non-error condition.
MM_INFO
Informative message.
MM_NOSEV
No severity level provided for the message.
MM_PRINT
Display message on standard error.
MM_CONSOLE
Display message on system console.

The table below indicates the null values and identifiers for fmtmsg() arguments. The <fmtmsg.h> header shall define the symbolic constants in the Identifier column, which shall have the type indicated in the Type column:

ArgumentTypeNull-ValueIdentifier
labelchar *(char*)0MM_NULLLBL
severityint0MM_NULLSEV
classlong0LMM_NULLMC
textchar *(char*)0MM_NULLTXT
actionchar *(char*)0MM_NULLACT
tagchar *(char*)0MM_NULLTAG

The <fmtmsg.h> header shall also define the following symbolic constants for use as return values for fmtmsg():

MM_OK
The function succeeded.
MM_NOTOK
The function failed completely.
MM_NOMSG
The function was unable to generate a message on standard error, but otherwise succeeded.
MM_NOCON
The function was unable to generate a console message, but otherwise succeeded.

The following shall be declared as a function and may also be defined as a macro. A function prototype shall be provided.

int fmtmsg(long, const char *, int,
    const char *, const char *, const char *);

The following sections are informative.
