getfile
getfile(poid, opts, rendition, ud)
This callback corresponds to the
sess_get_file function and retrieves an object (usually a graphic object) from the document repository. This callback can be used to override the rendition of the file that is retrieved.
• poid — the logical ID for the repository object
• opts — an integer value representing the desired operation
The following opts values are available:
◦ 1 indicates a request to read the contents
◦ 2 indicates a request to write to the contents
• rendition — the desired rendition of a graphic object; value must match one of the notations declared in your data model
• ud — user defined information; strings must match the adapter encoding
The getfile callback returns the following string:
• "IO_ERR_NOMORE" — the normal getfile routine should be performed
• If any other string is returned, the callback succeeded and the returned string represents the name of the local file that was created. The normal getfile function should not be performed.
