From f06a6f75ed02e0780d65d22498926af2eafc947a Mon Sep 17 00:00:00 2001 From: Hans Bolinder Date: Wed, 31 Aug 2011 09:26:43 +0200 Subject: Update documentation and specifications of some of the zlib functions The functions zlib:deflateSetDictionary/2 and zlib:inflateSetDictionary/2 accept iodata() as Dictionary. The functions zlib:crc32/2,3, zlib:adler32/2,3, zlib:compress/1, zlib:uncompress/1, zlib:zip/1, and zlib:unzip/1 accept iodata() as data. --- erts/doc/src/zlib.xml | 60 +++++++++++++++++++++++++-------------------------- 1 file changed, 30 insertions(+), 30 deletions(-) (limited to 'erts/doc') diff --git a/erts/doc/src/zlib.xml b/erts/doc/src/zlib.xml index 47a649af02..8917ab5c3a 100644 --- a/erts/doc/src/zlib.xml +++ b/erts/doc/src/zlib.xml @@ -378,31 +378,31 @@ unpack(Z, Compressed, Dict) -> Calculate CRC -
