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
|
|
utilty 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:"

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 preceed 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 - Variable function parameter 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)
|
