SYNOPSIS
size_t
bson_writer_get_length (bson_writer_t *writer);
PARAMETERS
- writer
- A bson_writer_t \&.
DESCRIPTION
Fetches the current length of the content written by the buffer (including the initial offset). This includes a partly written document currently being written.
This is useful if you want to check to see if you've passed a given memory boundry that cannot be sent in a packet. See bson_writer_rollback(3) to abort the current document being written.
RETURNS
The length of the underlying buffer.
