NAME

       pfmt(), vpfmt() - display message in standard format

SYNOPSIS

DESCRIPTION

       The  system  call  can be used to write a message in standard format to stream.	It can also be used to write a localized string to stream.
       The arguments to are formatted using style formatting.  is similar to except that the  arguments  are  passed  in  an  argument	list  (see
       stdarg(5)).

       The standard format displayed on stream has the following fields:

       The  label  string  is defined through setlabel(3C).  If no label is defined, this field is not used.  The severity string is controlled by
       the severity group of flags.  The text string is the formatted user string.

       The flags control how formatting is done.  The control information is separated into several different groups.  Only  one  flag	from  each
       group should be set.

	      Output Format

		     Do not use the standard format.
					 Treat fmt as a format string.	In this mode, only flags related to catalog access can be set.

		     Format using the standard format
					 is the default).

	      Catalog Access

		     Do not access the localized message catalog.
					 Use the def_str (a field in fmt) as the format string.

		     Access the localized message catalog
					 is the default).

	      Severity

		     Display a localized string.

		     Display a localized string is the default).

		     Display a localized string.

		     Display a localized string.

		     Besides  these  reserved  severities,  additional severity strings may be defined by the user (see addsev(3C)).  To specify a
		     user defined severity, flags should be a logical-or of the numeric value of the user defined severity and	flags  from  other
		     control groups.

	      Action

		     This flag generates the localized string of
					 in  the  severity field of the standard format message.  If this flag and flags from the severity control
					 group are set, this flag has precedence and the string will be displayed.

       The fmt string has the following fields:

       The catalog is the message catalog created by mkmsgs(1) where the localized message is to be retrieved.	The msg_number is a positive index
       number identifying the string to be retrieved from the message catalog (begins at 1).  The def_str is the default string to use if fails to
       retrieve the message from catalog from either the current locale or the default locale.	The failure may occur if the message catalog  does
       not exist or if the msg_number is out of bound.

       If catalog is not specified, uses the message catalog defined by setcat(3C).  If is set in flags, only def_str must be specified.

       The system call displays under the following conditions:

	 o  No message catalog is specified in fmt and no catalog is defined via setcat(3C).

	 o  msg_number is not positive.

	 o  No message could be retrieved and def_str is not specified.

RETURN VALUE

       If successful, and return the number of bytes written.  Otherwise, they return a negative value.

EXAMPLES

       generates the message:

   Example 4
       generates the message:
