NAME
ckdlivopts - check delivery notification options
SYNOPSIS
int ckdlivopts(int tcopy_hdr, int *svopts)
DESCRIPTION
Check if delivery notification requested for message being
processed. Returns specified options as combined from H_DEFOPTS,
H_TROPTS, & H_TCOPY lines.
(Positive notification options)
001 ==> /delivery requested
002 ==> /nodelivery requested
(Negative notification options)
010 ==> /report requested
020 ==> /return requested
040 ==> /ignore requested
Combinations are expected, i.e. - 011 ==> /delivery/report
If not specified, the assumed defaults are /nodelivery/return (rc=022)
The options discovered in the header are stored into svopts.
