From b7effd4e8338f6ed5bda630ad7ed0809bf458648 Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Mon, 21 Feb 2011 16:43:01 +0100 Subject: avio: avio_ prefixes for get_* functions In the name of consistency: get_byte -> avio_r8 get_ -> avio_r get_buffer -> avio_read get_partial_buffer will be made private later get_strz is left out becase I want to change it later to return something useful.
