fmtmsg.h - message display structures
The <fmtmsg.h> header shall define the following macros, which expand to constant integer expressions:
The following shall be declared as a function and may also be defined as a macro. A function prototype shall be provided.
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 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 otherwise succeeded.
int fmtmsg(long, const char *, int, const char *, const char *, const char *);
