/* SUMMARY

/* SYNOPSIS
/* #include <rcpt_buf.h>
/*
/* typedef struct {
/* RECIPIENT rcpt; /* convenience */
/* .in +4
/* VSTRING *address; /* final recipient */
/* VSTRING *orig_addr; /* original recipient */

/* int flags;
/* void *ptr;
/* DESCRIPTION
/* RECIPIENT_FROM_RCPT_BUF() populates the rcpt member with
/* a shallow copy of the contents of the other fields.
/*
/* rcpb_scan() reads a recipient buffer from the named stream
/* using the specified attribute scan routine. rcpb_scan()
/* is meant to be passed as a call-back to attr_scan(), thusly:
/*
/* ... ATTR_TYPE_FUNC, rcpb_scan, (void *) rcpt_buf, ...
/*
/* rcpb_create(), rcpb_reset() and rcpb_free() create, wipe
/* and destroy recipient buffer instances.
/* DIAGNOSTICS
/* Fatal: out of memory.
/* LICENSE
/* .ad
/* .fi
