Buffers
NAN's node::Buffer
helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.
Nan::NewBuffer()
Allocate a new node::Buffer
object with the specified size and optional data. Calls node::Buffer::New()
.
Note that when creating a Buffer
using Nan::NewBuffer()
and an existing char*
, it is assumed that the ownership of the pointer is being transferred to the new Buffer
for management. When a node::Buffer
instance is garbage collected and a FreeCallback
has not been specified, data
will be disposed of via a call to free()
. You must not free the memory space manually once you have created a Buffer
in this way.
Signature:
Nan::CopyBuffer()
Similar to Nan::NewBuffer()
except that an implicit memcpy will occur within Node. Calls node::Buffer::Copy()
.
Management of the char*
is left to the user, you should manually free the memory space if necessary as the new Buffer
will have its own copy.
Signature:
Nan::FreeCallback()
A free callback that can be provided to Nan::NewBuffer()
. The supplied callback will be invoked when the Buffer
undergoes garbage collection.
