/*++
Routine Description:
Prints an error message.
Arguments:
All arguments are optional, though the printed message may be useless if
at least something valid is not specified.
FileName - name of the file or application. If not specified, then the
utility name (as set by the utility calling SetUtilityName()
earlier) is used. Otherwise "Unknown utility" is used.
LineNumber - the line number of error, typically used by parsers. If the
utility is not a parser, then 0 should be specified. Otherwise
the FileName and LineNumber info can be used to cause
MS Visual Studio to jump to the error.
MessageCode - an application-specific error code that can be referenced in
other documentation.
Text - the text in question, typically used by parsers.
MsgFmt - the format string for the error message. Can contain formatting
controls for use with the varargs.
Returns:
None.
Notes:
We print the following (similar to the Warn() and Debug()
W
Typical error/warning message format:
bin\VfrCompile.cpp(330) : error C2660: 'AddVfrDataStructField' : function does not take 2 parameters
BUGBUG -- these three utility functions are almost identical, and
should be modified to share code.
Visual Studio does not find error messages with:
" error :"
" error 1:"
" error c1:"
" error 1000:"
" error c100:"
It does find:
" error c1000:"

/*++
Routine Description:
Worker routine for all the utility printing services. Prints the message in
a format that Visual Studio will find when scanning build outputs for
errors or warnings.
Arguments:
Type - "warning" or "error" string to insert into the message to be
printed. The first character of this string (converted to uppercase)
is used to precede the MessageCode value in the output string.
FileName - name of the file where the warning was detected, or the name
of the application that detected the warning
LineNumber - the line number where the warning was detected (parsers).
0 should be specified if the utility is not a parser.
MessageCode - an application-specific warning code that can be referenced in
other documentation.
Text - part of the message to print
MsgFmt - the format string for the message. Can contain formatting
controls for use with varargs.
List - the variable list.
Returns:
None.
Notes:
If FileName == NULL then this utility will use the string passed into SetUtilityName().
LineNumber is only used if the caller is a parser, in which case FileName refers to the
file being parsed.
Text and MsgFmt are both optional, though it would be of little use calling this function with
them both NULL.
Output will typically be of the form:
<FileName>(<LineNumber>) : <Type> <Type[0]><MessageCode>: <Text> : <MsgFmt>
Parser (LineNumber != 0)
VfrCompile.cpp(330) : error E2660: AddVfrDataStructField : function does not take 2 parameters
Generic utility (LineNumber == 0)
