gpointer jsc_value_typed_array_get_data ( JSCValue* value, gsize* length )
Obtains a pointer to the memory region that holds the elements of the typed
length is not
NULL, the number of elements contained in the typed array
are also stored in the pointed location.
The returned pointer needs to be casted to the appropriate type (see
JSCTypedArrayType), and has the
offset over the underlying array
buffer data applied—that is, points to the first element of the typed array:
if (jsc_value_typed_array_get_type(value) != JSC_TYPED_ARRAY_UINT32) g_error ("Only arrays of uint32_t are supported"); gsize count = 0; uint32_t *elements = jsc_value_typed_array_get_contents (value, &count); for (gsize i = 0; i < count; i++) g_print ("index %zu, value %" PRIu32 "\n", i, elements[i]);
Note that the pointer returned by this function is not guaranteed to remain
the same after calls to other JSC API functions. See
jsc_value_array_buffer_get_data() for details.
