Declaration [src]

g_bytes_new_from_bytes (
  GBytes* bytes,
  gsize offset,
  gsize length

Description [src]

Creates a GBytes which is a subsection of another GBytes. The offset + length may not be longer than the size of bytes.

A reference to bytes will be held by the newly created GBytes until the byte data is no longer needed.

Since 2.56, if offset is 0 and length matches the size of bytes, then bytes will be returned with the reference count incremented by 1. If bytes is a slice of another GBytes, then the resulting GBytes will reference the same GBytes instead of bytes. This allows consumers to simplify the usage of GBytes when asynchronously writing to streams.
