-* 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_hdrdrror error in the header portion
