+* Read spool header file *
+*************************************************/
+
+/* This function reads a spool header file and places the data into the
+appropriate global variables. The header portion is always read, but header
+structures are built only if read_headers is set true. It isn't, for example,
+while generating -bp output.
+
+It may be possible for blocks of nulls (binary zeroes) to get written on the
+end of a file if there is a system crash during writing. It was observed on an
+earlier version of Exim that omitted to fsync() the files - this is thought to
+have been the cause of that incident, but in any case, this code must be robust
+against such an event, and if such a file is encountered, it must be treated as
+malformed.
+
+As called from deliver_message() (at least) we are running as root.
+
+Arguments:
+ name name of the header file, including the -H
+ read_headers TRUE if in-store header structures are to be built
+ subdir_set TRUE is message_subdir is already set
+
+Returns: spool_read_OK success
+ spool_read_notopen open failed
+ spool_read_enverror error in the envelope portion
+ spool_read_hdrerror error in the header portion
