From cc193f1f0b45e4e65f246f1d5e6e8134844aa35b Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Sun, 2 Jan 2011 21:06:32 -0600 Subject: vcs-svn: allow character-oriented input buffer_read_char can be used in place of buffer_read_string(1) to avoid consuming valuable static buffer space. The delta applier will use this to read variable-length integers one byte at a time. Underneath, it is fgetc, wrapped so the line_buffer library can maintain its role as gatekeeper of input. Later it might be worth checking if fgetc_unlocked is faster --- most line_buffer functions are not thread-safe anyway.
