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.

RETURNS
The length of the underlying buffer.
