In this - * mode, most floating point constants are given as arrays - * of octal integers to eliminate decimal to binary conversion - * errors that might be introduced by the compiler. - * - * For computers, such as IBM PC, that follow the IEEE - * Standard for Binary Floating Point Arithmetic (ANSI/IEEE - * Std 754-1985), the symbol IBMPC should be defined. These - * numbers have 53-bit significands. In this mode, constants - * are provided as arrays of hexadecimal 16 bit integers. - * - * To accommodate other types of computer arithmetic, all - * constants are also provided in a normal decimal radix - * which one can hope are correctly converted to a suitable - * format by the available C language compiler. To invoke - * this mode, the symbol UNK is defined. - * - * An important difference among these modes is a predefined - * set of machine arithmetic constants for each. The numbers - * MACHEP (the machine roundoff error), MAXNUM (largest number - * represented), and several other parameters are preset by - * the configuration symbol. Check the file const.c to - * ensure that these values are correct for your computer. - * - * For ANSI C compatibility, define ANSIC equal to 1.

- char *<[s]>; - char **<[ptr]>; - -DESCRIPTION - The function <<strtosfix16>> converts the string <<*<[s]>>> to - a fixed-point sign + 15-bits fraction representation. The function - follows the same rules as <<strtod>>. - - The substring converted is the longest initial - subsequence of <[s]>, beginning with the first - non-whitespace character, that has the format: - .[+|-]<[digits]>[.][<[digits]>][(e|E)[+|-]<[digits]>] - The substring contains no characters if <[s]> is empty, consists - entirely of whitespace, or if the first non-whitespace - character is something other than <<+>>, <<->>, <<.>>, or a - digit. If the substring is empty, no conversion is done, and - the value of <[s]> is stored in <<*<[ptr]>>>. Otherwise, - the substring is converted, and a pointer to the final string - (which will contain at least the terminating null character of - <[s]>) is stored in <<*<[ptr]>>>. If you want no - assignment to <<*<[ptr]>>>, pass a null pointer as <[ptr]>. - - <<strtosfix32>> is identical to <<strtosfix16>> except that it - converts to fixed-point sign + 31-bits fraction representation. - <<strtosfix64>> is also similar, except that it converts - to fixed-point sign + 63-bit fraction format. - - The alternate functions <<_strtosfix16_r>>, <<_strtosfix32_r>>, - and <<_strtosfix64_r>> are reentrant versions. - The extra argument <[reent]> is a pointer to a reentrancy structure. - -RETURNS - The functions return the converted substring value, if any. If - no conversion can be performed, then 0 is returned. If the converted - value is a NaN, 0 is returned and errno is set to <<EDOM>>. - If the converted value exceeds the maximum positive fixed-point value, - the output value is saturated to the maximum value and <<ERANGE>> is stored in - errno. If the converted value is less than the minimum fixed-point negative - value, then the output is saturated to the minimum value and <<ERANGE>> is stored - in errno.

- -DESCRIPTION -<<vprintf>>, <<vfprintf>>, <<vsprintf>> and <<vsnprintf>> are (respectively) -variants of <<printf>>, <<fprintf>>, <<sprintf>> and <<snprintf>>. They differ -only in allowing their caller to pass the variable argument list as a -<<va_list>> object (initialized by <<va_start>>) rather than directly -accepting a variable number of arguments. - -RETURNS -The return values are consistent with the corresponding functions: -<<vsprintf>> returns the number of bytes in the output string, -save that the concluding <<NULL>> is not counted. -<<vprintf>> and <<vfprintf>> return the number of characters transmitted. -If an error occurs, <<vprintf>> and <<vfprintf>> return <<EOF>>. No -error returns occur for <<vsprintf>>. - -PORTABILITY -ANSI C requires all three functions. - -Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>, -<<lseek>>, <<read>>, <<sbrk>>, <<write>>. -*/ - -/*- - * Copyright (c) 1990 The Regents of the University of California. - * All rights reserved. - * - * This code is derived from software contributed to Berkeley by - * Chris Torek. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.
