Declaration [src]
JSCValue*
jsc_value_new_typed_array_with_buffer (
JSCValue* array_buffer,
JSCTypedArrayType type,
gsize offset,
gssize length
)
Description [src]
Create a new typed array value with elements from an array buffer.
Create a JSCValue referencing a new typed array value containing
elements of the given type, where the elements are stored at the memory
region represented by the array_buffer.
The type must not be JSC_TYPED_ARRAY_NONE.
The offset and length parameters can be used to indicate which part of
the array buffer can be accessed through the typed array. If both are
omitted (passing zero as offset, and -1 as length), the whole
array_buffer is exposed through the typed array. Omitting the length
with a non-zero offset will expose the remainder of the array_buffer
starting at the indicated offset.
