Yes, I've glimpsed into that by following it since Xen 4.1.
I am indeed compiling an application against libxc.

Thanks, that's a very gracious offer. Well, here's what nm has to say
about what I'm using from the Xen libraries:

xc_copy_to_domain_page
xc_domain_decrease_reservation_exact
xc_domain_get_tsc_info
xc_domain_getinfo
xc_domain_hvm_getcontext_partial
xc_domain_pause
xc_domain_populate_physmap_exact
xc_domain_set_access_required
xc_domain_set_pagefault_info
xc_domain_shutdown
xc_domain_unpause
xc_evtchn_bind_interdomain
xc_evtchn_close
xc_evtchn_fd
xc_evtchn_notify
xc_evtchn_open
xc_evtchn_pending
xc_evtchn_unbind
xc_evtchn_unmask
xc_get_hvm_param
xc_get_mem_access
xc_interface_close
xc_interface_open
xc_map_foreign_batch
xc_map_foreign_range
xc_mem_access_disable
xc_mem_access_enable
xc_mem_access_resume
xc_set_hvm_param
xc_set_mem_access
xc_translate_foreign_address
xc_vcpu_getcontext
xc_vcpu_setcontext
xc_version
xs_close
xs_directory
xs_fileno
xs_is_domain_introduced
xs_open
xs_read
xs_read_watch
xs_unwatch
xs_watch

Libxl is, unfortunately, too high-level for our needs.


Thanks,
