[pdftex] \pdfmapfile -- test if the mapfile could be found?

[Martin Schröder]

Hi,
is there any way in pdfTeX or for the caller of pdfTeX to find
out if the mapfile specified by \pdfmapfile was found and could
be read without errors by pdfTeX? 

pdfTeX only prints out a warning if it can't find the file and
succeeds. :-{

Best regards
        Martin
