The output is displayed on \fIstream\fR. 23 .sp 24 .LP 25 The \fBpfmt()\fR function encapsulates the output in the standard error message 26 format (unless \fBMM_NOSTD\fR is specified, in which case the output is similar 27 to \fBprintf()\fR). 28 .sp 29 .LP 30 If the \fBprintf()\fR format string is to be retrieved from a message database, 31 the \fBformat\fR argument must have the following structure: 32 .sp 33 .LP 34 \fI<catalog>\fR\fB:\fR\fI<msgnum>\fR\fB:\fR\fI<defmsg>\fR\&. 35 .sp 36 .LP 37 If \fBMM_NOGET\fR is specified, only the \fIdefmsg\fR field must be specified. 38 .sp 39 .LP 40 The \fIcatalog\fR field is used to indicate the message database that contains 41 the localized version of the format string. This field must be limited to 14 42 characters selected from the set of all characters values, excluding \fB\e0\fR 43 (null) and the ASCII codes for \fB/\fR (slash) and \fB:\fR (colon). 44 .sp 45 .LP 46 The \fImsgnum\fR field is a positive number that indicates the index of the 47 string into the message database. 48 .sp 49 .LP 50 If the catalog does not exist in the locale (specified by the last call to 51 \fBsetlocale\fR(3C) using the \fBLC_ALL\fR or \fBLC_MESSAGES\fR categories), or 52 if the message number is out of bound, \fBpfmt()\fR will attempt to retrieve 53 the message from the C locale. If this second retrieval fails, \fBpfmt()\fR 54 uses the \fIdefmsg\fR field of the \fBformat\fR argument. 55 .sp 56 .LP 57 If \fIcatalog\fR is omitted, \fBpfmt()\fR will attempt to retrieve the string 58 from the default catalog specified by the last call to \fBsetcat\fR(3C). In 59 this case, the \fBformat\fR argument has the following structure: 60 .sp 61 .LP 62 \fB:\fR\fI<msgnum>\fR\fB:\fR\fI<defmsg>\fR\&. 63 .sp 64 .LP 65 The \fBpfmt()\fR will output \fBMessage not found!!\en\fR as format string if 66 \fIcatalog\fR is not a valid catalog name, if no catalog is specified (either 67 explicitely or with \fBsetcat()\fR), if \fImsgnum\fR is not a valid number, or 68 if no message could be retrieved from the message databases and \fIdefmsg\fR 69 was omitted. 70 .sp 71 .LP 72 The \fIflags\fR argument determine the type of output (such as whether the 73 \fBformat\fR should be interpreted as is or encapsulated in the standard 74 message format), and the access to message catalogs to retrieve a localized 75 version of \fBformat\fR. 76 .sp 77 .LP 78 The \fIflags\fR argument is composed of several groups, and can take the 79 following values (one from each group): 80 .sp 81 .LP 82 \fIOutput format control\fR 83 .sp 84 .ne 2 85 .na 86 \fB\fBMM_NOSTD\fR\fR 87 .ad 88 .RS 12n 89 Do not use the standard message format, interpret \fBformat\fR as 90 \fBprintf()\fR \fBformat\fR.

The specified severity will be generated from the bitwise 171 \fBOR\fR operation of the numeric value and other \fIflags\fR If the severity 172 is not defined, \fBpfmt()\fR uses the string \fBSEV=\fR\fIN\fR, where \fIN\fR 173 is replaced by the integer severity value passed in \fIflags\fR. 174 .sp 175 .LP 176 Multiple severities passed in \fIflags\fR will not be detected as an error. Any 177 combination of severities will be summed and the numeric value will cause the 178 display of either a severity string (if defined) or the string 179 \fBSEV=\fR\fIN\fR (if undefined). 180 .sp 181 .LP 182 \fIAction\fR 183 .sp 184 .ne 2 185 .na 186 \fB\fBMM_ACTION\fR\fR 187 .ad 188 .RS 13n 189 Specify an action message.
