I hope you like the subject matter and I hope it is not too
simplistic or have been answered before.
Anyway I have a question about how the garbage collector works
in a very specific situation. When passing string type to a
function in a shared library or DLL and assigning it to a
variable of type string inside the function and returning the
internal string. Such as this.
export string mytest(string tstStr)
{
string st = tstStr;
/* abbreviated to protect the innocent but other operations
such as concatenating and deleting may be done to st before
the return
*/
return st;
}
Is the string type a pointer or is it something else? In the
line where tstStr is assigned to st does it copy the address in
tstStr to st or does it copy the value in tstStr? I am just a
bit confused about string types since I come from a C background
and C has no type like this. Also what is returned by this
function? Does this function return a pointer or the contents of
an array? If I do export this what does it do to the Garbage
Collection? Does the Garbage Collection collect tstStr or st?
Also notice the comment in the function.
