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 Iden- tifier column, which expand to constant 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 succeeded.
MM_NOCON The function was unable to generate a console message, but oth- erwise succeeded.
The following shall be declared as a function and may also be defined as a macro. A function prototype shall be provided.
int fmtmsg(long, const char *, int, const char *, const char *, const char *);
The following sections are informative.
APPLICATION USAGE None.
FUTURE DIRECTIONS None.
