DataView objects
(byte-level typed data access on ArrayBuffer
s).
This module allows to read and write buffers with any data element at any byte offset.
The type for DataView objects.
of_buffer ~byte_offset ~length b k
provides access to byte_length
(defaults to Buffer.byte_length b
) bytes of b
starting at byte offset byte_offset
.
val byte_offset : t -> int
byte_offset d
is the byte index where d
starts in buffer d
.
val byte_length : t -> int
byte_length d
is the byte length of d
.
