| ARGUMENTS | 
    
    | Argument | Description |  
    | dkim | 
	A message signing handle.
	 |  
    | hdrlist | 
	A NULL-terminated array of strings containing the names of header
	fields to be included in the hashes that generate this signature.

| NOTES |  
- This overides the list of header field names previously selected as the
library default by a call to
dkim_options().  It affects only the
handle passed to the function.  If not called, the default set configured for
this library instance is used.
