A quick problem. In my C code (which represents functions on an
object), if an argument is wrong, I throw an exception. Right now, I
do this:
JS_SetPendingException(cx,script_string_to_value("my error text"));
script_string_to_value is just a wrapper to turn the string into a
JSVAL.
This works fine. When reacting to the error (in C), I get the
pending exception, check if it's a string, then use the string. If
it's not a string, then JS itself throws and exception, and I can call:
report=JS_ErrorFromException(cx,errval);
And get the report.
The problem: When I make an exception, I don't get the line numbers
and other information. I want to be able (in C) to construct a
exception like the engine itself does, so I can have the line numbers
where it occurred. Calling:
JS_ReportError(cx,"my error text");
Doesn't work, as it's not an exception (maybe this is my problem, and
I don't understand this correctly.) So, what solutions do I have?
