Subject: ZSTDMT_endStream : nullify input buffer after flush
X-Git-Tag: v1.1.3^2~19^2~35
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6073b3e6b86488d1d6963b7dbf3fedf34ac7158e;p=thirdparty%2Fzstd.git

ZSTDMT_endStream : nullify input buffer after flush

There will be no more input after ZSTDMT_endStream invocation :
only flush/end is allowed (to fully collect compressed result).
