[PATCH 2/9] gitweb: change die_error to take "extra" argument for extended die information

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

 



This is a small change that just adds a 3rd, optional, parameter to die_error
that allows for extended error information to be output along with what the
error was.
