Subject: Return null instead of throwing if a file is not found in sources
X-Git-Url: http://git.tdb.fi/?p=libs%2Fdatafile.git;a=commitdiff_plain;h=00795982c9a99dcad69b33f75d38328165bd5df8

Return null instead of throwing if a file is not found in sources

The primary use case for open_from_sources is for creator functions to
open raw files.  This change makes it easier to gracefully skip a non-
existent file and carry on with other ways of loading the item.
