* libc: Purge unneeded cdefs.hWarner Losh2023-11-011-1/+0
| | | | | | | | | These sys/cdefs.h are not needed. Purge them. They are mostly left-over from the $FreeBSD$ removal. A few in libc are still required for macros that cdefs.h defines. Keep those. Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D42385

* Fix -Wvoid-pointer-to-enum-cast warnings.Brooks Davis2020-04-151-3/+3
| | | | | | | | | | | | | | | | | This pattern is used in callbacks with void * data arguments and seems both relatively uncommon and relatively harmless. Silence the warning by casting through uintptr_t. This warning is on by default in Clang 11.

* libc: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-251-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. 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. Notes: svn path=/head/; revision=326193

* - The ai_addrlen of a struct addrinfo used to be a size_t, perHajimu UMEMOTO2005-05-151-3/+8
| | | | | | | | | | | | | | | | | | | RFC 2553. In XNS5.2, and subsequently in POSIX-2001 and RFC 3493, it was changed to a socklen_t. And, the n_net of a struct netent used to be an unsigned long integer. In XNS5, and subsequently in POSIX-2001, it was changed to an uint32_t. To accomodate for this while preserving ABI compatibility with the old interface, we need to prepend or append 32 bits of padding, depending on the (LP64) architecture's endianness. - Correct 1st argument of getnetbyaddr() to uint32_t on 32 bit arch. Stay as is on 64 bit arch for ABI backward compatibility for now. Reviewed by: das, peter MFC after: 2 weeks Notes: svn path=/head/; revision=146244

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch Notes: svn path=/head/; revision=71579
