Checking out Enterpirse PDM files with SW2010 API code

[Killswitch2]

I'm creating a marco that opens a series of drawings (in my EPDM vault) and creates a PDF of each. I'd like to overwrite any existing PDF files with the new version. What I'm stuggling with is if the existing PDF isn't checked out by the user, the new one can't be saved.

Is there code that I can include in the macro that checks out each existing PDF before the save_as and then checks them back in after the new version is saved.

I'd like this to be transparent to the macro user.

Thanks,
