zfs code - Dec 2008 - does libzfs header in Solaris 10U5 match the code?

I have to build an application I have written on SXCE on Solaris 10 update 5 and
I''ve hit a snag with the prototype for zfs_send:

#pragma ident   "@(#)libzfs.h   1.4     08/01/09 SMI"

extern int zfs_send(zfs_handle_t *, const char *, int);

which appears to predate incremental snapshots.

Is this the correct prototype for the supplied libzfs?  If so, how were
incremental sends implemented?
 
Thanks,

Sorry for the noise, I found the matching source and I''d misinterpreted
the "tosnap" parameter in the current source.
