Folks,
I am looking into some legacy code that is called from a third-party
library. The function being called has this signature:
AStringClass PlatformSpecificImplClass::formatMessage(unsigned int
code,
va_list* argList)
The problem is that on x86 platforms, |argList| seems to point to a
valid
4-byte unicode string "(null)", but on PPC, this string appears to be
garbled. I say "appears to be" because I can't actually tell, since
in
Xcode I have no visibility into |argList|. Is there a way I can
examine the
contents of this pointer?
va_list is generally treated as an opaque type (it's defined in
stdarg.h). If you know exactly how it's laid out, you can try
something like
(gdb) x/4x argList
but don't assume anything about its layout outside a debugging context.
