function fillpdf_merge_perform_pdf_action in FillPDF 7

Figure out what to do with the PDF and do it.

Normally, this calls drupal_exit(). In error conditions, it returns void.

Parameters

object $fillpdf_object: Metadata object, usually generated by _fillpdf_build_options_object().

string $action: One of the following keywords: default, download, save, redirect. These correspond to performing the configured action (from admin/structure/fillpdf/%), sending the PDF to the user's browser, saving it to a file, and saving it to a file and then redirecting the user's browser to the saved file.

bool $force_download: If set, this function will always end the request by sending the filled PDF to the user's browser.

Here, specifically, it's for generating the filename of the handled PDF.
