Hi folks,
I'd like to wrap a family of C functions that look like this:
gboolean fooXXX(arg1, ..., argN, GError** err)
Their signatures and arities vary, but they all have a GError** as
their last argument. If a function returns false, then 'err' will be
set to a relevant Error struct.
I would like to write a wrapper that would let me call these functions
sort of like this:
check!(fooXXX(arg1, ..., argN))
where the 'check' expression would be equivalent to:
GError* err;
bool ok = fooXXX(arg1, ..., argN, &err);
if (!ok)
throw new Exception((*err).message);
Does D (2.0) offer a metaprogramming technique I could use to
accomplish this -- particularly, to inject that 'err' argument into
the tail of the fooXXX call?
Thanks,
Graham
