NAME
       fmtmsg.h - message display structures

SYNOPSIS
       #include <fmtmsg.h>

DESCRIPTION
       The  <fmtmsg.h> header shall define the following macros, which expand to constant integer
       expressions:

       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 macros in the Identifier column, which expand to con-
       stant expressions that expand to expressions of 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 macros 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 suc-
	      ceeded.

       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  func-
       tion prototype shall be provided.

	      int fmtmsg(long, const char *, int,
		  const char *, const char *, const char *);

       The following sections are informative.

APPLICATION USAGE
       None.

RATIONALE
       None.

FUTURE DIRECTIONS
