* Replace our ancient dtoa/strtod implementation with the gdtoaDavid Schultz2003-03-121-9/+10
| | | | | | | | | | | | | | | | | | | | | package, a more recent, generalized set of routines. Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.

| | | | | | | | | | | | | In original version grouping was hardcoded. It assumed that thousands separator should be inserted to separate each 3 numbers. I.e. grouping string "\003" was assumed for all cases. In correct case (per POSIX) vfprintf should respect locale defined non-monetary (LC_NUMERIC category) grouping sequence.

* Remove _THREAD_SAFE and make libc thread-safe by default byDaniel Eischen2001-01-241-62/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch Notes: svn path=/head/; revision=71579

* Add FILE locking stubs for libc.John Birrell1998-04-111-17/+6
| | | | | | | | | | | Change the FILE locking to support kernel threads when linked with libpthread (which you haven't see yet). This requires that libc become thread-safe and thread-aware, testing __isthreaded before attempting to do lock/unlock calls. The impact on non-threaded programs is minor. This change works with libc_r, so it's the best compromise. Notes: svn path=/head/; revision=35129

* Suggested by: Bruce Evans, Jeffrey Hsu, Gary PalmerJames Raynard1996-06-221-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | Added $Id$'s to files that were lacking them (gpalmer), made some cosmetic changes to conform to style guidelines (bde) and checked against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde) One last code cleanup:- Removed spurious casts in fseek.c and stdio.c. Added missing function argument in fwalk.c. Added missing header include in flags.c and rget.c. Put in casts where int's were being passed as size_t's. Put in missing prototypes for static functions. Changed second args of __sflags() inflags.c and writehook() in vasprintf.c from char * to const char * to conform to prototypes. This directory now compiles with no warnings with -Wall under gcc-2.6.3 and with considerably less warnings than before with the ultra-pedantic script I used for testing. (Most of the remaining ones are due to const poisoning). Notes: svn path=/head/; revision=16586
