SYNOPSIS

9       #include <fmtmsg.h>
10

DESCRIPTION

12       The  <fmtmsg.h>  header shall define the following macros, which expand
13       to constant integer expressions:
14
15       MM_HARD
16              Source of the condition is hardware.
17
18       MM_SOFT
19              Source of the condition is software.
20
21       MM_FIRM
22              Source of the condition is firmware.
23
24       MM_APPL
25              Condition detected by application.
26
27       MM_UTIL
28              Condition detected by utility.
29
30       MM_OPSYS
31              Condition detected by operating system.
32
33       MM_RECOVER
34              Recoverable error.
35
36       MM_NRECOV
37              Non-recoverable error.
38
39       MM_HALT
40              Error causing application to halt.
41
42       MM_ERROR
43              Application has encountered a non-fatal fault.
44
45       MM_WARNING
46              Application has detected unusual non-error condition.
47
48       MM_INFO
49              Informative message.
50
51       MM_NOSEV
52              No severity level provided for the message.
53
54       MM_PRINT
55              Display message on standard error.
56
57       MM_CONSOLE
58              Display message on system console.
59
60
61       The table below indicates the null values and identifiers for  fmtmsg()
62       arguments.   The <fmtmsg.h> header shall define the macros in the Iden‐
63       tifier column, which expand to  constant  expressions  that  expand  to
64       expressions of the type indicated in the Type column:
65
66
67                     Argument   Type     Null-Value   Identifier
68                     label      char *   (char*)0     MM_NULLLBL
69                     severity   int      0            MM_NULLSEV
70                     class      long     0L           MM_NULLMC
71                     text       char *   (char*)0     MM_NULLTXT
72                     action     char *   (char*)0     MM_NULLACT
73                     tag        char *   (char*)0     MM_NULLTAG
74
75       The <fmtmsg.h> header shall also define the following macros for use as
76       return values for fmtmsg():
77
78       MM_OK  The function succeeded.
79
80       MM_NOTOK
81              The function failed completely.
82
83       MM_NOMSG
84              The function was unable to generate a message on standard error,
85              but otherwise succeeded.
86
87       MM_NOCON
88              The  function was unable to generate a console message, but oth‐
89              erwise succeeded.
90
91
92       The following shall be declared as a function and may also  be  defined
93       as a macro. A function prototype shall be provided.
94
95
96              int fmtmsg(long, const char *, int,
97                  const char *, const char *, const char *);
