+ Purpose
+ =======
+ Reads an Internet message (RFC 5322), or one or more messages
+ stored in a maildrop in mbox (RFC 4155) or MMDF format, from a file
+ stream. Each call to m_getfld() reads one header field, or a
+ portion of the body, in sequence.
+
+ Inputs
+ ======
+ gstate: opaque parse state
+ bufsz: maximum number of characters to load into buf
+ iob: input file stream
+
+ Outputs
+ =======
+ name: header field name (array of size NAMESZ=999)
+ buf: either a header field body or message body
+ bufsz: number of characters loaded into buf
+ (return value): message parse state on return from function
+
+ Functions
+ =========
+ void m_getfld_state_destroy (m_getfld_state_t *gstate): destroys
+ the parse state pointed to by the gstate argument.
+
+ m_getfld_state_reset (m_getfld_state_t *gstate): resets the parse
+ state to FLD.
+
+ void m_unknown(FILE *iob): Determines the message delimiter string
+ for the maildrop. Called by inc, scan, and msh when reading from a
+ maildrop file.
+
+ void m_eomsbr (int (*action)(int)): Sets the hook to check for end
+ of message in a maildrop. Called only by msh.
+
+ State variables
+ ===============
+ m_getfld() retains state internally between calls in the
+ m_getfld_state_t variable. These are used for detecting the end of
+ each message when reading maildrops:
+
+ unsigned char **pat_map
+ unsigned char *fdelim
+ unsigned char *delimend
+ int fdelimlen
+ unsigned char *edelim
+ int edelimlen
+ char *msg_delim
+ int msg_style
+ int (*eom_action)(int)
+
+ Usage
+ =====
+ m_getfld_state_t gstate = 0;
+ ...
+ int state = m_getfld (&gstate, ...);
+ ...
+ m_getfld_state_destroy (&gstate);
+
+ The state is retained internally by gstate. To reset its state to FLD:
+ m_getfld_state_reset (&gstate);

+/* The following described the old implementation. The high-level
+ structure hasn't changed, but some of the details have. I'm

+
/* This module has a long and checkered history. First, it didn't burst
maildrops correctly because it considered two CTRL-A:s in a row to be
an inter-message delimiter. It really is four CTRL-A:s followed by a
it knows that _filbuf ignores the _ptr & _cnt and simply fills
the buffer. If stdio on your system doesn't work this way, you
may have to make small changes in this routine.
-
+
This routine also "knows" that an EOF indication on a stream is
"sticky" (i.e., you will keep getting EOF until you reposition the
stream). If your system doesn't work this way it is broken and you
there is data in "name" or "buf").
