ecos为实时嵌入式操作系统

	* tests/i18n/setlocale.c:
	New tests for setlocale()

	* tests/PKGconf.mak:
	Update to build setlocale.c test

	* src/support/cstartup.cxx: 
	Don't actually call system default main() "main" otherwise GDB
	gets confused and thinks its the entry point. Instead make a weak
	alias and call the real function something different.

Tue Sep  1 18:31:42 1998  Jonathan Larmour  <[e-mail]>

	* src/i18n/locale.cxx (_setlocale): 
	Fix tracing macro name and remove "str maybe used before
	initialised" warning

	* tests/stdlib/qsort.c: 
	Correct file description header

Tue Sep  1 17:04:32 1998  Jonathan Larmour  <[e-mail]>

	* include/locale.h, src/clibincl/i18nsupp.hxx, src/i18n/locale.cxx:
	New files to add support for locales as defined by the ISO C
	standard. i.e. setlocale() and localeconv() functions and some
	other bits

	* include/pkgconf/libc.h:
	Add CYGNUM_LIBC_MAX_LOCALE_NAME_SIZE config option for locale
	support

	* src/PKGconf.mak:
	build locale.cxx
	
	* include/errno.h, src/clibincl/ctypesupp.hxx: 
	Tidy up to 76 columns

Tue Sep  1 00:24:22 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h:
	Move environment-related options from stdlib into new
	CYGPKG_LIBC_STARTUP component. Also add options for main()'s
	arguments (CYGPKG_LIBC_ARGUMENTS), main()'s default stack size
	(CYGNUM_LIBC_MAIN_STACK_SIZE), number of atexit handlers
	(CYGNUM_LIBC_ATEXIT_HANDLERS), and whether _exit() stops the
	system (CYGSEM_LIBC_EXIT_STOPS_SYSTEM).

	* src/clibincl/stdlibsupp.hxx:
	Fix a few comment bugs, and add new
	cyg_libc_invoke_atexit_handlers() function prototype

	* src/stdlib/_exit.cxx, src/stdlib/atexit.cxx, src/stdlib/exit.cxx:
	Implement exit(), atexit() and _exit() correctly now. Also
	includes cyg_libc_invoke_atexit_handlers() in atexit.cxx. Now
	we get the correct behaviour of atexit(), and exit() invokes the
	atexit handlers and fflushs all the stdio streams. Add plenty of
	tracing of asserts too.

	* src/support/cstartup.cxx: 
	Make main_thread object an exported global. Allow user-settable
	arguments. Add MUCH more tracing and asserts. Improve comments.
	Tidy up to 76 columns

	* tests/stdlib/atexit.c:
	Add simple test for atexit() and it calling registered functions

	* tests/PKGconf.mak:
	Build atexit.c test

Mon Aug 31 18:54:48 1998  Jonathan Larmour  <[e-mail]>

	* src/stdlib/getenv.cxx, tests/stdlib/getenv.c:
	Add support for getenv(), and some tests to ensure it works

	* src/PKGconf.mak, tests/PKGconf.mak:
	Update to include getenv.cxx and getenv.c test

	* src/clibincl/clibdata.hxx:
	remove prototype for environ - we expect files needing it to
	define it themselves

	* src/support/clibdata.cxx:
	Tidy up to 76 columns and add definition of char **environ, but
	with a configurable initialiser (see libc.h below)

	* tests/stdlib/abs.c (main): 
	Tidy up to 76 columns

	* src/stdlib/malloc.cxx: 
	Tidy up to 76 columns and remove warning for undefined _memcpy()
	by changing to memcpy(), and casting away signedness

	* include/pkgconf/libc.h:
	Add CYGPKG_LIBC_ENVIRONMENT and CYGDAT_LIBC_DEFAULT_ENVIRONMENT
	configuration options

	* include/pkgconf/libc.h, src/clibincl/clibdata.hxx: 
	Tidy up to 76 columns

	* include/stdlib.h: 
	Add getenv() prototype and tidy up to 76 columns

	* src/clibincl/stdlibsupp.hxx: 
	Add _getenv() prototype
	
Mon Aug 31 13:37:08 1998  Jonathan Larmour  <[e-mail]>

	* src/stdlib/malloc.cxx:
	Add realloc()

	* tests/stdlib/realloc.c:
	Add this file to test new realloc() functionality

	* tests/PKGconf.mak:
	Build realloc test

	* tests/stdlib/malloc3.c (main), tests/stdlib/malloc2.c (main),
	  tests/stdlib/malloc1.c (main): 
	Conditionalise local vars to prevent warnings

	* tests/stdlib/malloc3.c (fill_with_data): 
	Move '{' into "verb" line

	* include/pkgconf/libc.h: 
	Require infra tracing support to allow tracing

	* include/stdlib.h:
	Add realloc()

	* src/clibincl/stdlibsupp.hxx: 
	Update the commented argument names from stdlib.h, including realloc()

1998-08-28  Bart Veer  <[e-mail]>

	* include/pkgconf/libc.h:
	* src/clibincl/clibdata.hxx, src/time/clock.cxx:
	
	Updated for new kernel configuration option symbol names

Fri Aug 28 19:18:25 1998  Hugo Tyson  <[e-mail]>

	Changed the entry below to sat "tx39" instead of "mn10300".
	It's been a long week.

Fri Aug 28 18:59:20 1998  Hugo Tyson  <[e-mail]>

	* src/support/cstartup.cxx: Add a weakly named main to allow the
 	default configuration to link on the tx39 which has no
 	scalextric linking yet.  The static Cyg_Thread main_thread object
 	below continues to exist, though unreferenced, so all its
 	descendants must exist too.

Fri Aug 28 08:54:29 1998  Jonathan Larmour  <[e-mail]>

	* include/stdlib.h: 
	Add commented argument names Add exit(), and atexit(). And move
 	these along with abort() and _exit() to a new section.

	Add trivial versions of atexit() and exit()

	* include/pkgconf/libc.h:
	Add CYGNUM_LIBC_MAIN_STACK_SIZE config option

	* include/sys/cstartup.h, src/support/cstartup.cxx, src/PKGconf.mak:
	New files to provide a new function cyg_iso_c_support(), which
	invokes main "correctly".

Fri Aug 28 00:29:38 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/stream.cxx: 
	Add #ifdef CYGSEM_LIBC_STDIO_WANT_BUFFERED_IO around all accesses to

Tue Aug 25 15:10:57 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h: 
	Tidy up CDL stuff a bit more, prior to checking it actually works.

Tue Aug 25 11:38:52 1998  Jonathan Larmour  <[e-mail]>

	* tests/stdlib/malloc2.c (main):

Tue Aug 18 16:10:03 1998  Jonathan Larmour  <[e-mail]>

	as recommended by the config name rules


Tue Aug 18 14:31:19 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/setvbuf.cxx (_setvbuf): 
	Rename variable names in assert line, otherwise doesn't build
	with asserts on!

Sun Aug 16 18:15:12 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/input/vfscanf.cxx (_vfscanf): 
	Fix some bugs, although there are some left to fix still. Unrelated
	to the rest of the checkins, so I will check the partial fix in now.

	* src/clibincl/stream.hxx, src/clibincl/stream.inl,
	  src/stdio/common/stream.cxx:
	Add parameters to constructor to allow more things to be done at
	construction time.

	Now we have "new", remove separate "construct" method

	Add more documentation on constructor

	As requested by code review, where possible, move boolean flags
	into separate packed bitfield structure for space efficiency

	Make readbuf_char be usable all the time rather than when configured
	not to be buffering, as it is also needed for non-buffered mode i.e.
	_IONBF

	* src/stdio/common/fopen.cxx:
	Change to use new method of construction from above, using new

	Use thread-specific data, rather than global. And so change errnos
	to access errno entry specifically

	Make process_mode() check for append mode too

	Reformat for coding standards to have { in same line as "verb"

	* src/stdio/common/setvbuf.cxx:

	Change to cope with different way of dealing with buffering policy
	flags etc. in Cyg_StdioStream

	* src/stdio/common/vsnprintf.cxx, src/stdio/common/vsscanf.cxx,
	  src/support/clibdata.cxx:
	Change construction of streams to use new parameters added above,
	and change to use _IONBF mode for string stdio functions,
	otherwise its a waste of memory. And use _IONBF for stderr as the
	ISO standard tells us to!

	Reformat for coding standards to have { in same line as "verb"

	* src/clibincl/streambuf.hxx, src/clibincl/streambuf.inl:
	Change constructor so that it can be set with default size and
	dynamic buffer (if applicable)

	Fix minor bug in destructor - should only call free when allocated
	dynamically

	Change get_buffer_size to return -1 if the buffer was not allowed
	to be set up

	* src/stdio/common/streambuf.cxx:
	Remove unnecessary stdio.h include and add extra comment to whether
	to free bit in set_buffer()

	* src/stdio/common/freopen.cxx:
	Change @@@ to standard fix me string

	* src/stdio/output/fputc.cxx:
	Remove unnecessary "written" variable

Thu Aug 13 15:37:28 1998  Jonathan Larmour  <[e-mail]>

	* src/stdlib/_exit.cxx: 
	Included use of "fix me" line to ensure this is discussed before
	release

	* include/stdlib.h, src/stdlib/abort.cxx, src/PKGconf.mak:
	Add abort.cxx to implement abort(), albeit naively

Thu Jul 30 18:03:09 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/vsscanf.cxx (_vsscanf),
	  src/stdio/common/vsnprintf.cxx (_vsnprintf): 
	Fix initialiser of pseudo string device table that didn't get updated
	when the table changed (Bad proven, no biscuit).

	* src/clibincl/stream.inl (~Cyg_StdioStream):
