From 9c64d2a7ba6feb196099ee8b65bba163191008c0 Mon Sep 17 00:00:00 2001 From: Jeff Johnston Date: Mon, 9 Sep 2002 21:42:14 +0000 Subject: 2002-09-09 Jeff Johnston * libc/include/sys/_types.h (_mbstate_t): Changed to use unsigned char internally. * libc/sys/linux/sys/_types.h: Ditto. * libc/include/sys/reent.h * libc/stdlib/mblen.c (mblen): Use function-specific state value from default reentrancy structure. * libc/stdlib/mblen_r.c (_mblen_r): If return code from _mbtowc_r is less than 0, reset state __count value and return -1. * libc/stdlib/mbrlen.c (mbrlen): If the input state pointer is NULL, use the function-specific pointer provided in the default reentrancy structure. * libc/stdlib/mbrtowc.c: Add reentrant form of function. If input state pointer is NULL, use function-specific area provided in reentrancy structure. * libc/stdlib/mbsrtowcs.c: Ditto. * libc/stdlib/wcrtomb.c: Ditto. * libc/stdlib/wcsrtombs.c: Ditto. * libc/stdlib/mbstowcs.c: Reformat. * libc/stdlib/wcstombs.c: Ditto. * libc/stdlib/mbstowcs_r.c (_mbstowcs_r): If an error occurs, reset the state's __count value and return -1. * libc/stdlib/mbtowc.c: Ditto. * libc/stdlib/mbtowc_r.c (_mbtowc_r): Add restartable functionality. If number of bytes is used up before completing a valid multibyte character, return -2 and save the state. * libc/stdlib/wctomb_r.c (_wctomb_r): Define __state as __count and change some __count references to __state for clarity. --- newlib/libc/stdlib/mbrlen.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'newlib/libc/stdlib/mbrlen.c') diff --git a/newlib/libc/stdlib/mbrlen.c b/newlib/libc/stdlib/mbrlen.c index 8f0c648b9..504348d38 100644 --- a/newlib/libc/stdlib/mbrlen.c +++ b/newlib/libc/stdlib/mbrlen.c @@ -7,7 +7,13 @@ size_t mbrlen(const char *s, size_t n, mbstate_t *ps) { - mbstate_t internal; +#ifdef MB_CAPABLE + if (ps == NULL) + { + _REENT_CHECK_MISC(_REENT); + ps = &(_REENT_MBRLEN_STATE(_REENT)); + } +#endif - return mbrtowc(NULL, s, n, ps != NULL ? ps : &internal); + return mbrtowc(NULL, s, n, ps); } -- cgit v1.2.3
