VarPtr
Pointer = VarPtr ( Variable )
Returns a pointer that points at the
Variable contents in memory.
-
Variable must be a local variable, or a global variable of the current class.
-
The datatype of the variable must be a number, a date, or a pointer.
-
It can be a string only for global variables. In that case, the returned pointer is not the address of the string contents, but the address of a pointer that points at the string contents.
Since 3.15
-
Variable can be a Variant too. But beware, the returned pointer is guaranteed to be valid until the datatype of the variant changes.
Use this function when an extern function argument is a pointer to a numeric variable.
For example,
int *, or
void **.
Do not use it to deal with
char **, because the contents of a Gambas string variable is read-only.
