assignPtr()
The function allows to assign a shared_ptr to a different shared_ptr..
Synopsis
int assignPtr(shared_ptr &target, shared_ptr source);
Parameter
-
Parameter Description target Target shared_ptr to which the source shared_ptr is assigned. The "target" pointer is detached from the original source before assigning the new "source" pointer. source shared_ptr that should be assigned.
Return Value
Success returns 0; in case of an invalid argument returns -1
Errors
The function returns an exception in case the shared_ptr objects are not compatible.
Description
The function allows to assign a shared_ptr to another shared_ptr. Before assigning the "source" pointer to the "target" pointer a null pointer is assigned to the "target" and therefore overridden and detached.
The same result can be achieved using following code:
target = nullptr;
target = source;The function unpacks the target parameter. E.g.:
dyn_anytype da;
da[1] = new int(1); //this creates an anytype which itself holds a shared_ptr which points to an int
assignPtr(da[1], new int(8));Assignment
