Sending a stream file to the browser
(download a stream file)
|On Dec 30, 2012, CGISRVPGM2 has been added subprocedures DspStmf() and DnlStmf().
Both procedures are sending a specified stream file to the browser, but are slightly different.
- Subprocedure DspStmf() (Display a stream file) leaves to the browser the decision whether to display or to download the stream file.
Usually a browser decides to display a stream file if it has a pluging to do it (as an example, Internet Explorer has a pluging to display a PDF),
otherwise it downloads the stream file (asks the user whether to open the stream file with the appropriate program or to save it).
- Subprocedure DnlStmf() (Download a stream file) forces the browser to download the stream file (the browser asks the user whether to open the stream file with the appropriate program or to save it).
In case of failure, check the joblog and/or the CGIDEBUG file for a detail error message.
D xstmf s 1024 varying
D rc s 10i 0
// rc is 0 when successful, -1 when failed
You may try CGI program stmfToBrow which takes advantage of subprocedures DspStmf and DnlStmf.
Note - Since March 13, 2016 procedures DspStmf() and DnlStmf() can handle stream files even larger than 16 MB.
