Hello,
This was posted to the BSON group<https://groups.google.com/forum/?fromgroups#!topic/bson/aKr6CPiGIyI>,
but no one has viewed it yet, so cross-posting here in hope that some one
can help.
I am working on a standalone BSON C++ API<http://kenai.com/projects/mongoviewer/sources/svn/show/bson?rev=106>.
At present I have a couple of issues with my BSON serialiser, so am using
the C API to generate the bson. I do not see any functions to set the size
(the first 4 bytes of the document/sub-document as per spec) of the BSON
data, neither could I find anything appropriate in the test suite for the C
driver. bsondump generates the following error trace when I use it to read
my test bson output
It may be that my logic is false when generating the BSON. The basic
workflow is as follows:
::bson b;
bson_init_size( &b, document.getSize() );
// iterator over elements in document and based on element type invoke appropriate bson_append_xxx functions
bson_finish( &b );
bson_destroy( &b );
bsondump /tmp/doctest.bson
{ "_id" : ObjectId( "506b931b44c193650000feff" ), "double" : 1, "string" :
"string value", undefined, "boolean" : true, "date" : Date( 1349209034000
), "null" : null, "regex" : /^abc/, "integer" : 1, "long" : 2 }

Any idea what I am missing when using the C API for serialising to BSON?
Thanks
