Subject: added test for ZSTD_initCStream_advanced()
X-Git-Tag: v1.2.0^2~34^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0bb381dad88105946728d04c3ea45c19204c2636;p=thirdparty%2Fzstd.git

added test for ZSTD_initCStream_advanced()

when params.fParams.contentSizeFlags = 1
and pledgedSrcSize = 0
then srcSize should be considered 0 (empty), and not "unknown"
