fmtmsg.h(0P) POSIX Programmer's Manual fmtmsg.h(0P)
This manual page is part of the POSIX Programmer's Manual. The
Linux 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.
fmtmsg.h — message display structures
#include <fmtmsg.h>
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:
┌──────────┬────────┬────────────┬────────────┐
│ 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 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.
None.
None.
None.
