How do I print the filename in awk?

I have an issue where I am trying to find pdf files that contain pdfx: (metadata) in Windows.

I have cygwin installed but grep is giving me the same results for:

Code:

grep 'pdfx:' *.pdf

as for:

Code:

grep -v 'pdfx:' *.pdf

I can find the information in the files using gawk:

Code:

gawk '(/pdfx:/)' *.pdf

However, what I need is the filename.

Is there a way of printing the filename in gawk?

Code:

gawk '/pdfx:/{print FILENAME; nextfile}' *.pdf

In awk the built-in variable FILENAME stores the name of the current input file (if any).
