29*7c478bd9Sstevel@tonic-gate SYNOPSIS
30*7c478bd9Sstevel@tonic-gate int ckdlivopts(int tcopy_hdr, int *svopts)
31*7c478bd9Sstevel@tonic-gate
32*7c478bd9Sstevel@tonic-gate DESCRIPTION
33*7c478bd9Sstevel@tonic-gate Check if delivery notification requested for message being
34*7c478bd9Sstevel@tonic-gate processed. Returns specified options as combined from H_DEFOPTS,
35*7c478bd9Sstevel@tonic-gate H_TROPTS, & H_TCOPY lines.
36*7c478bd9Sstevel@tonic-gate
37*7c478bd9Sstevel@tonic-gate (Positive notification options)
38*7c478bd9Sstevel@tonic-gate 001 ==> /delivery requested
39*7c478bd9Sstevel@tonic-gate 002 ==> /nodelivery requested
40*7c478bd9Sstevel@tonic-gate (Negative notification options)
41*7c478bd9Sstevel@tonic-gate 010 ==> /report requested
42*7c478bd9Sstevel@tonic-gate 020 ==> /return requested
43*7c478bd9Sstevel@tonic-gate 040 ==> /ignore requested
44*7c478bd9Sstevel@tonic-gate
45*7c478bd9Sstevel@tonic-gate Combinations are expected, i.e. - 011 ==> /delivery/report
46*7c478bd9Sstevel@tonic-gate If not specified, the assumed defaults are /nodelivery/return (rc=022)
47*7c478bd9Sstevel@tonic-gate
48*7c478bd9Sstevel@tonic-gate The options discovered in the header are stored into svopts.
