Define *_t types except for pid_t also for __USE_XOPEN. Define S_* macros also for __USE_XOPEN. * locale/langinfo.h: Define CODESET, CRNCYSTR, RADIXCHAR, and THOUSEP also for __USE_XOPEN. * math/math.c: Define M_* macros also for __USE_XOPEN. * math/bits/mathcalls.h: Declare hypot also for __USE_XOPEN. * posix/fnmatch.h: Define FNM_NOSYS and for if _XOPEN_SOURCE is defined. * posix/glob.h: Likewise for GLOB_NOSYS. * posix/regex.h: Likewise for REG_NOSYS. * posix/wordexp.h: Likewise for WRDE_NOSYS. * posix/unistd.h: Define *_t types also for __USE_XOPEN. * posix/sys/wait.h: Define pid_t for __USE_XOPEN. * pwd/pwd.h: Define gid_t and pid_t also for __USE_XOPEN. * signal/signal.h: Define pid_t also fir __USE_XOPEN. * sysdeps/unix/sysv/linux/bits/fcntl.h: Define _RSYNC and O_DSYNC also for __USE_POSIX199309. * sysdeps/unix/sysv/linux/bits/termios.h: Define the various B* constants also for __USE_XOPEN. * wcsmbs/wchar.h: For XPG4 include wctype.h. * intl/dcgettext.c (find_msg): Initialize act to prevent warning. * locale/setlocale.c (new_composite_name): Likewise for last_len. * libio/stdio.h: Don't declare fclose_unlocked. * sysdeps/posix/fpathconf.c: Handle _PC_FILESIZEBITS. 1998-07-08 Mark Kettenis * stdio/stdio.h: Add prototypes for fflush_unlocked, getc_unlocked, getchar_unlocked, putc_unlocked, putchar_unlocked, fgets_unlocked, fread_unlocked, fwrite_unlocked, clearerr_unlocked, feof_unlocked, ferror_unlocked, fileno_unlocked, flockfile, ftrylockfile, funlockfile. [__USE_XOPEN && !__USE_GNU] Declare optarg, optind, opterr. Add prototype for getopt. * stdio/clearerr.c (clearerr_unlocked): Weak alias for clearerr. * stdio/feof.c (feof_unlocked): Weak alias for feof. * stdio/ferror.c (ferror_unlocked): Weak alias for ferror. * stdio/fflush.c (fflush_unlocked): Weak alias for fflush. * stdio/fgets.c (fgets_unlocked): Weak alias for fgets. * stdio/fileno.c (fileno_unlocked): Weak alias for fileno. * stdio/fputc.c (fputc_unlocked): Weak alias for fputc. * stdio/fread.c (fread_unlocked): Weak alias for fread. * stdio/fwrite.c (fwrite_unlocked): Weak alias for fwrite. * stdio/getc.c (getchar_unlocked): Weak alias for getc. * stdio/getchar.c (getchar_unlocked): Weak alias for getchar. * stdio/putc.c (putc_unlocked): Weak alias for putc. * stdio/putchar.c (putchar_unlocked): Weak alias for putchar. * stdio/Versions [GLIBC_2.1]: Add clearerr_unlocked, feof_unlocked, ferror_unlocked, fflush_unlocked, fgets_unlocked, fileno_unlocked, fputc_unlocked, fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked, putc_unlocked and putchar_unlocked. * libio/Versions: Move flockfile, ftrylockfile and funlockfile from here ... * stdio-common/Versions: ... to here. 1998-07-09 Andreas Jaeger * Makerules (versioning): Correct typo. --- stdio/stdio.h | 118 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 118 insertions(+) (limited to 'stdio/stdio.h') diff --git a/stdio/stdio.h b/stdio/stdio.h index dd4dd6db0d..eac8bd41b1 100644 --- a/stdio/stdio.h +++ b/stdio/stdio.h @@ -333,6 +333,11 @@ extern int fclose __P ((FILE *__stream)); /* Flush STREAM, or all streams if STREAM is NULL. */ extern int fflush __P ((FILE *__stream)); +#ifdef __USE_MISC +/* Faster versions when locking is not required. */ +extern int fflush_unlocked __P ((FILE *__stream)); +#endif + #ifdef __USE_GNU /* Close all streams. */ extern int __fcloseall __P ((void)); @@ -543,6 +548,26 @@ getchar (void) } #endif /* Optimizing. */ +#if defined __USE_POSIX || defined __USE_MISC +/* These are defined in POSIX.1:1996. */ +extern int getc_unlocked __P ((FILE *__stream)); +extern int getchar_unlocked __P ((void)); + +# ifdef __OPTIMIZE__ +extern __inline int +getc_unlocked (FILE *__stream) +{ + return __getc (__stream); +} + +extern __inline int +getchar_unlocked (void) +{ + return __getc (stdin); +} +# endif /* Optimizing. */ +#endif /* Use POSIX or MISC. */ + /* Write a character to STREAM. */ extern int fputc __P ((int __c, FILE *__stream)); @@ -571,6 +596,39 @@ putchar (int __c) } #endif +#ifdef __USE_MISC +/* Faster version when locking is not necessary. */ +extern int fputc_unlocked __P ((int __c, FILE *__stream)); + +# ifdef __OPTIMIZE__ +extern __inline int +fputc_unlocked (int __c, FILE *__stream) +{ + return __putc (__c, __stream); +} +# endif /* Optimizing. */ +#endif /* Use MISC. */ + +#if defined __USE_POSIX || defined __USE_MISC +/* These are defined in POSIX.1:1996. */ +extern int putc_unlocked __P ((int __c, FILE *__stream)); +extern int putchar_unlocked __P ((int __c)); + +# ifdef __OPTIMIZE__ +extern __inline int +putc_unlocked (int __c, FILE *__stream) +{ + return __putc (__c, __stream); +} + +extern __inline int +putchar_unlocked (int __c) +{ + return __putc (__c, stdout); +} +# endif /* Optimizing. */ +#endif /* Use POSIX or MISC. */ + #if defined __USE_SVID || defined __USE_MISC /* Get a word (int) from STREAM. */ @@ -585,6 +643,12 @@ extern int putw __P ((int __w, FILE *__stream)); extern char *fgets __P ((char *__restrict __s, int __n, FILE *__restrict __stream)); +#ifdef __USE_GNU +/* This function does the same as `fgets' but does not lock the stream. */ +extern char *fgets_unlocked __P ((char *__restrict __s, int __n, + FILE *__restrict __stream)); +#endif + /* Get a newline-terminated string from stdin, removing the newline.
