2007-11-27 Juerg Billeter <j@bitron.ch> * gbufferedinputstream.c: (g_buffered_input_stream_peek_buffer), (g_buffered_input_stream_read_byte): * gbufferedinputstream.h: New functions for efficient access to buffer and simple single byte reads. * gdatainputstream.c: (scan_for_newline), (scan_for_chars), (g_data_input_stream_read_until): * gdatainputstream.h: Use peek_buffer to avoid memcpy in scan_for_newline, implement read_until with multiple stop chars. svn path=/trunk/; revision=5952
