implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
NAMEfmtmsg.h - message display structures
SYNOPSIS
#include <fmtmsg.h>
DESCRIPTION
The <fmtmsg.h> header shall define the following macros, which expand
to constant integer expressions:
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 macros in the Iden‐
tifier column, which expand to constant expressions that expand to
expressions of the type indicated in the Type column:
Argument Type Null-Value Identifier
label char * (char*)0 MM_NULLLBL
severity int 0 MM_NULLSEV
class long 0L MM_NULLMC
text char * (char*)0 MM_NULLTXT
action char * (char*)0 MM_NULLACT
tag char * (char*)0 MM_NULLTAG
The <fmtmsg.h> header shall also define the following macros 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 oth‐
erwise 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.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.
