From 5665b0e1d06cf7df8403ff287c8d400ebd368c65 Mon Sep 17 00:00:00 2001 From: Jeff Johnston Date: Mon, 1 Oct 2001 18:05:11 +0000 Subject: 2001-10-01 Charles Wilson * libc/include/stdlib.h: add declarations for _strtoull_r, _strtoll_r, strtoull, and strtoll. * libc/stdio/local.h: remove declarations of __strtoull_r and __strtoll_r. * libc/stdio/vfscanf.c(__svfscanf_r): call _strtoull_r instead of __strtoull_r. Ditto _strtoll_r vs. __strtoll_r. * libc/stdlib/Makefile.am: add new files to .c list and .def list * libc/stdlib/Makefile.in: regenerate * libc/stdlib/strtoll_r.c: rename __strtoll_r as _strtoll_r * libc/stdlib/strtoull_r.c: rename __strtoull_r as _strtoull_r * libc/stdlib/strtoull.c: new file * libc/stdlib/strtoll.c: new file --- newlib/libc/stdlib/strtoll.c | 138 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 138 insertions(+) create mode 100644 newlib/libc/stdlib/strtoll.c (limited to 'newlib/libc/stdlib/strtoll.c') diff --git a/newlib/libc/stdlib/strtoll.c b/newlib/libc/stdlib/strtoll.c new file mode 100644 index 000000000..fdba09f24 --- /dev/null +++ b/newlib/libc/stdlib/strtoll.c @@ -0,0 +1,138 @@ +/* +FUNCTION + <>---string to long long + +INDEX + strtoll +INDEX + _strtoll_r + +ANSI_SYNOPSIS + #include + long long strtoll(const char *<[s]>, char **<[ptr]>,int <[base]>); + + long long _strtoll_r(void *<[reent]>, + const char *<[s]>, char **<[ptr]>,int <[base]>); + +TRAD_SYNOPSIS + #include + long strtoll (<[s]>, <[ptr]>, <[base]>) + char *<[s]>; + char **<[ptr]>; + int <[base]>; + + long _strtoll_r (<[reent]>, <[s]>, <[ptr]>, <[base]>) + char *<[reent]>; + char *<[s]>; + char **<[ptr]>; + int <[base]>; + +DESCRIPTION +The function <> converts the string <<*<[s]>>> to +a <>. First, it breaks down the string into three parts: +leading whitespace, which is ignored; a subject string consisting +of characters resembling an integer in the radix specified by <[base]>; +and a trailing portion consisting of zero or more unparseable characters, +and always including the terminating null character. Then, it attempts +to convert the subject string into a <> and returns the +result. + +If the value of <[base]> is 0, the subject string is expected to look +like a normal C integer constant: an optional sign, a possible `<<0x>>' +indicating a hexadecimal base, and a number. If <[base]> is between +2 and 36, the expected form of the subject is a sequence of letters +and digits representing an integer in the radix specified by <[base]>, +with an optional plus or minus sign. The letters <>--<> (or, +equivalently, <>--<>) are used to signify values from 10 to 35; +only letters whose ascribed values are less than <[base]> are +permitted. If <[base]> is 16, a leading <<0x>> is permitted. + +The subject sequence is the longest initial sequence of the input +string that has the expected form, starting with the first +non-whitespace character. If the string is empty or consists entirely +of whitespace, or if the first non-whitespace character is not a +permissible letter or digit, the subject string is empty. + +If the subject string is acceptable, and the value of <[base]> is zero, +<> attempts to determine the radix from the input string. A +string with a leading <<0x>> is treated as a hexadecimal value; a string with +a leading 0 and no <> is treated as octal; all other strings are +treated as decimal. If <[base]> is between 2 and 36, it is used as the +conversion radix, as described above. If the subject string begins with +a minus sign, the value is negated. Finally, a pointer to the first +character past the converted subject string is stored in <[ptr]>, if +<[ptr]> is not <>. + +If the subject string is empty (or not in acceptable form), no conversion +is performed and the value of <[s]> is stored in <[ptr]> (if <[ptr]> is +not <>). + +The alternate function <<_strtoll_r>> is a reentrant version. The +extra argument <[reent]> is a pointer to a reentrancy structure. + +RETURNS +<> returns the converted value, if any. If no conversion was +made, 0 is returned. + +<> returns <> or <> if the magnitude of +the converted value is too large, and sets <> to <>. + +PORTABILITY +<> is nonstandard. + +No supporting OS subroutines are required. +*/ + +/*- + * Copyright (c) 1990 The Regents of the University of California. + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
