Winedbg & symbols

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



this patch adds a new command to winedbg
info symbol <s>
where <s> is a regular expression
it'll display all known symbols match regex <s>

I made the assumption that regex (header, lib) was standard across unices. if not, let me know & I'll add the configure bits

A+
