From dd0ee2e1022843c6a296a9141b7cab7ea74eec28 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 30 Aug 2002 07:07:16 +0000 Subject: Update. 2002-08-29 Ulrich Drepper * libio/fileops.c (_IO_new_file_fopen): Recognize new mode specifier 'm' to enable mmap I/O. * libio/libio.h (_IO_FILE): Rename _blksize field to _flags2. The former wasn't used (anymore?). (_IO_FLAGS2_MMAP): New define. * libio/genops.c (_IO_no_init): Initialize _flags2 field. * libio/iofopen.c (__fopen_maybe_mmap): Use mmap callbacks only if _IO_FLAGS2_MMAP bit is set. * libio/iofdopen.c (_IO_new_fdopen): Recognize 'm' mode specifier. Enable mmap-using mode only if 'm' was set. --- libio/libio.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'libio/libio.h') diff --git a/libio/libio.h b/libio/libio.h index c8231df..3c6bef9 100644 --- a/libio/libio.h +++ b/libio/libio.h @@ -137,6 +137,8 @@ #define _IO_BAD_SEEN 0x4000 #define _IO_USER_LOCK 0x8000 +#define _IO_FLAGS2_MMAP 1 + /* These are "formatting flags" matching the iostream fmtflags enum values. */ #define _IO_SKIPWS 01 #define _IO_LEFT 02 @@ -282,7 +284,11 @@ struct _IO_FILE { struct _IO_FILE *_chain; int _fileno; +#if 0 int _blksize; +#else + int _flags2; +#endif _IO_off_t _old_offset; /* This used to be _offset but it's too small. */ #define __HAVE_COLUMN /* temporary */ -- cgit v1.1
