The ovm_int_t
type is the OrchIDS incarnation of the data type of signed machine integers.
It is defined this way in src/lang.h:
typedef struct ovm_int_s ovm_int_t; struct ovm_int_s { gc_header_t gc; long val; };
This is a type of garbage-collectable data. To allocate a new object of type ovm_int_t
, use the function:
ovm_var_t *ovm_int_new(gc_t *gc_ctx, long val);
This creates a new ovm_int_t
object with value val
. Its return type is the universal type ovm_var_t
instead of ovm_int_t
, for practical reasons. Calling res
the result, one always has TYPE(res)==T_INT
.
The result is created white, and much be gc_touch()
ed before storing it into a garbage-collectable object.
The returned ovm_int_t
object res
is modifiable. One can read from or write from it by using the INT()
macro (e.g., int i=INT(res); INT(res) = 3;
).
