Buffer.with_owner

Description:

[ CCode ( has_construct_function = false ) ]
public Buffer.with_owner (uint8[] data, void* owner, DestroyNotify? owner_dnotify)

Creates a new Buffer containing data.length bytes from data .

When the Buffer is freed, it will call owner_dnotify, passing owner to it. You must ensure that data will remain valid until owner_dnotify is called.

For example, you could use this to create a buffer containing data returned from libxml without needing to do an extra copy:

xmlDocDumpMemory (doc, &xmlbody, &len);
return soup_buffer_new_with_owner (xmlbody, len, xmlbody,
                                   (GDestroyNotify)xmlFree);

In this example, data and owner are the same, but in other cases they would be different (eg, owner would be a object, and data would be a pointer to one of the object's fields).

Parameters:

data	data
owner	pointer to an object that owns `data`
owner_dnotify	a function to free/unref `owner` when the buffer is freed
length	length of `data`

Returns:

the new Buffer.
