MM_HARD

Source of the condition is hardware.

MM_SOFT

Source of the condition is software.

MM_FIRM

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_NOSEV

No severity level provided for the message.

MM_PRINT

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 symbolic constants 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 succeeded.

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 function prototype shall be provided.
