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 numeric, a pointer, or a string.

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.
