sam_mig_stage_write()
passes data from the foreign data migration program
to the file system for the stage associated with stage_req
(see sam_mig_stage_file (3)).
stage_req
is the number of this stage request. buffer is a pointer
to the data that needs to be transferred.
len is the number of bytes of data to transfer.
offset is the offset from the beginning of this stage request.
This is not the offset from the beginning of the file (keep in mind
stage_never).
sam_mig_stage_write
returns the actual number of bytes written.
Otherwise, a value of -1 is returned.
If an error is returned,
sam_mig_stage_end
should still be called.
The only function allowed on
stage_req
after an error is sam_mig_stage_end.
