* libc: Add strverscmp(3) and versionsort(3)Aymeric Wibo2022-08-251-0/+1
| | | | | | | | | | | | | | | Add a strverscmp(3) function to libc, a GNU extension I implemented by reading its glibc manual page. It orders strings following a much more natural ordering (e.g. "ent1 < ent2 < ent10" as opposed to "ent1 < ent10 < ent2" with strcmp(3)'s lexicographic ordering). Also add versionsort(3) for use as scandir(3)'s compar argument. Update manual page for scandir(3) and add one for strverscmp(3).

* include: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326024

| | | | | | | | | | | | | | | | | that the annotated function returns a pointer that doesn't alias any extant pointer. This results in a 50%+ speedup in microbenchmarks such as the following: char *cp = malloc(1), *buf = malloc(BUF); for (i = 0; i < BUF; i++) buf[i] = *cp; In real programs, your mileage will vary. Note that gcc already performs this optimization automatically for any function called `malloc', `calloc', `strdup', or `strndup' unless -fno-builtins is used. Notes: svn path=/head/; revision=187961
* Add strndup(3) prototype to string.h.Konstantin Belousov2008-12-081-0/+1
| | | | | | | | | | | | | | This change was erronously ommitted from the r185690, and attempt to simply add the prototype to string.h has revealed that several contributed programs defined local prototypes for strndup(), controlled by autoconfed config.h. So, manually change #undef HAVE_STRNDUP to #define HAVE_STRNDUP 1. Next import of the corresponding program would regenerate config.h, overriding the changes in this commit.

* Change the definition of NULL on ia64 (for LP64 compilations) fromMarcel Moolenaar2003-12-071-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | an int constant to a long constant. This change improves consistency in the following two ways: 1. The first 8 arguments are always passed in registers on ia64, which by virtue of the generated code implicitly widens ints to longs and allows the use of an 32-bit integral type for 64-bit arguments. Subsequent arguments are passed onto the memory stack, which does not exhibit the same behaviour and consequently do not allow this. In practice this means that variadic functions taking pointers and given NULL (without cast) work as long as the NULL is passed in one of the first 8 arguments. A SIGSEGV is more likely the result if such would be done for stack-based arguments. This is due to the fact that the upper 4 bytes remain undefined. 2. All 64-bit platforms that FreeBSD supports, with the obvious exception of ia64, allow 32-bit integral types (specifically NULL) when 64-bit pointers are expected in variadic functions by way of how the compiler generates code. As such, code that works correctly (whether rightfully so or not) on any platform other than ia64, may fail on ia64. To more easily allow tweaking of the definition of NULL, this commit removes the 12 definitions in the various headers and puts it in a new header that can be included whenever NULL is to be made visible. This commit fixes GNOME, emacs, xemacs and a whole bunch of ports that I don't particularly care about at this time... Notes: svn path=/head/; revision=123257
