Consider this:
I have a function FUNC, it takes a string array, and does
something with it, and retruns the same. Implemented based on a
previous thread, here is what i have
string[] FUNC (ref string[] ZZ)
{
/*
do something
*/
}
and the calling is, ZZ = FUNC(ZZ)
Now, I want, should the function be not successful in doing
what it intends to do, to return a boolean value of false, to
ZZ, un fortunately ZZ is already a string[] (so i want liek a C
style fopen -like function, that , although called with the
syntax: file *f = fopen(balh, "bla"); can set f to be false)
Is this possible in D?
You could use std.typecons.Nullable, std.variant.Variant, or
switch to using exceptions for error reporting.
