Re: Qp0lGetPathFromFileID how to check errors in AS400

Hi Steff

After the documentation about returning NULL is a list of error conditions. These are values of errno, which is mentioned there. You have a couple choices. First, you need to retrieve errno. There is a thread in this list with some help for you -

That link points to the post in the RPG list.

Hi

I'm reading a line from an IBM created journal and I want to display the name of the file that was accessed.
I'm using this API, and getting the results I want when everything is ok.

D GetPathFID PR * ExtProc('Qp0lGetPathFromFileID')
D buf * Value
D size 10U 0 Value
D fileid 16A
D rc s *

c clear buffer 512

c eval rc = GetPathFID(%ADDR(Buffer)
c : %SIZE(Buffer)
c : obj_fid )

Sometimes I get no result with this API, and the Buffer is empty, and rc gets SPP:*NULL.
After doing some reading on the IBM site, I understand that this means there is an error, but how do I retrieve the error?

Thank you
Steff
