The output is displayed on \fIstream\fR. If \fIstream\fR is \fINULL\fR no output is displayed. .sp .LP The \fBlfmt()\fR function encapsulates the output in the standard error message format (unless \fBMM_NOSTD\fR is specified, in which case the output is like that of \fBprintf()\fR. It forwards its output to the logging and monitoring facility, even if \fIstream\fR is \fINULL\fR. Optionally, \fBlfmt()\fR displays the output on the console with a date and time stamp. .sp .LP If the \fBprintf()\fR format string is to be retrieved from a message database, the \fBformat\fR argument must have the following structure: .sp .LP \fI\fR\fB:\fR\fI\fR\fB:\fR\fI\fR\&. .sp .LP If \fBMM_NOGET\fR is specified, only the \fI\fR field must be specified. .sp .LP The \fI\fR field indicates the message database that contains the localized version of the format string. This field is limited to 14 characters selected from a set of all characters values, excluding the null character (\fB\e0\fR) and the ASCII codes for slash (\fB/\fR) and colon (\fB:\fR). .sp .LP The \fI\fR field is a positive number that indicates the index of the string into the message database. .sp .LP If the catalog does not exist in the locale (specified by the last call to \fBsetlocale\fR(3C) using the \fBLC_ALL\fR or \fBLC_MESSAGES\fR categories), or if the message number is out of bound, \fBlfmt()\fR will attempt to retrieve the message from the C locale. If this second retrieval fails, \fBlfmt()\fR uses the \fI\fR field of the \fBformat\fR argument. .sp .LP If \fI\fR is omitted, \fBlfmt()\fR will attempt to retrieve the string from the default catalog specified by the last call to \fBsetcat\fR(3C). In this case, the \fBformat\fR argument has the following structure: .sp .LP \fB:\fR\fI\fR\fB:\fR\fI\fR\&. .sp .LP The \fBlfmt()\fR function will output the message .sp .LP \fBMessage not found!!\en\fR .sp .LP as the format string if \fI\fR is not a valid catalog name, if no catalog is specified (either explicitly or with \fBsetcat()\fR), if \fI\fR is not a valid number, or if no message could be retrieved from the message databases and \fI\fR was omitted. .sp .LP The \fIflags\fR argument determines the type of output (whether the \fBformat\fR should be interpreted as it is or be encapsulated in the standard message format) and the access to message catalogs to retrieve a localized version of \fBformat\fR. .sp .LP The \fIflags\fR argument is composed of several groups, and can take the following values (one from each group): .sp .ne 2 .na \fB\fIOutput format control\fR\fR .ad .sp .6 .RS 4n .sp .ne 2 .na \fB\fBMM_NOSTD\fR\fR .ad .RS 12n Do not use the standard message format but interpret \fBformat\fR as a \fBprintf()\fR \fBformat\fR. Only \fIcatalog access control flags\fR, \fIconsole display control\fR and \fIlogging information\fR should be specified if \fBMM_NOSTD\fR is used; all other flags will be ignored. .RE .sp .ne 2 .na \fB\fBMM_STD\fR\fR .ad .RS 12n Output using the standard message format (default value is 0). .RE .RE .sp .ne 2 .na \fB\fICatalog access control\fR\fR .ad .sp .6 .RS 4n .sp .ne 2 .na \fB\fBMM_NOGET\fR\fR .ad .RS 12n Do not retrieve a localized version of \fBformat\fR.

The specified severity is formed by the bitwise \fBOR\fR operation of the numeric value and other \fIflags\fR arguments. .sp If the severity is not defined, \fBlfmt()\fR uses the string \fBSEV=\fR\fIN\fR where \fIN\fR is the integer severity value passed in \fIflags\fR. .sp Multiple severities passed in \fIflags\fR will not be detected as an error. Any combination of severities will be summed and the numeric value will cause the display of either a severity string (if defined) or the string \fBSEV=\fR\fIN\fR (if undefined). .RE .sp .ne 2 .na \fB\fIAction\fR\fR .ad .sp .6 .RS 4n .sp .ne 2 .na \fB\fBMM_ACTION\fR\fR .ad .RS 13n Specify an action message.
