* Clarify getfsstat(2) usage.Alfred Perlstein2004-07-161-1/+6
| | | | | | | | | | | | The getfsstat(2) function expects a buffer and a count, and returns a count. The confusing part is that the count it takes is a byte count, while the return value is a count of the number of structures it has filled out. Spell this out. Notes: svn path=/head/; revision=132231

* Make regular expression matching aware of multibyte characters. The generalTim J. Robbins2004-07-125-324/+478
| | | | | | | | | | | | | | | | | | | | idea is that we perform multibyte->wide character conversion while parsing and compiling, then convert byte sequences to wide characters when they're needed for comparison and stepping through the string during execution. As with tr(1), the main complication is to efficiently represent sets of characters in bracket expressions. The old bitmap representation is replaced by a bitmap for the first 256 characters combined with a vector of individual wide characters, a vector of character ranges (for [A-Z] etc.), and a vector of character classes (for [[:alpha:]] etc.). One other point of interest is that although the Boyer-Moore algorithm had to be disabled in the general multibyte case, it is still enabled for UTF-8 because of its self-synchronizing nature. This greatly speeds up matching by reducing the number of multibyte conversions that need to be done. Notes: svn path=/head/; revision=132019
* Add a new error code, REG_ILLSEQ, to indicate that a regular expressionTim J. Robbins2004-07-122-1/+5

* Implement the classification macros isfinite(), isinf(), isnan(), andDavid Schultz2004-07-0917-501/+141
| | | | | | | | | | | | | | | | | | | | | | | | isnormal() the hard way, rather than relying on fpclassify(). This is a lose in the sense that we need a total of 12 functions, but it is necessary for binary compatibility because we have never bumped libm's major version number. In particular, isinf(), isnan(), and isnanf() were BSD libc functions before they were C99 macros, so we can't reimplement them in terms of fpclassify() without adding a dependency on libc.so.5. I have tried to arrange things so that programs that could be compiled in FreeBSD 4.X will generate the same external references when compiled in 5.X. At the same time, the new macros should remain C99-compliant. The isinf() and isnan() functions remain in libc for historical reasons; however, I have moved the functions that implement the macros isfinite() and isnormal() to libm where they belong. Moreover, half a dozen MD versions of isinf() and isnan() have been replaced with MI versions that work equally well. Prodded by: kris Notes: svn path=/head/; revision=131852
