Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header. 2020-01-18 09:38:21 +01:00			`/*`

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt * 2021-04-22 01:24:48 -07:00			`* SPDX-License-Identifier: BSD-2-Clause`

LibC: Add missing sys/cdefs.h include Some header files use __BEGIN_DECLS without including sys/cdefs.h. This causes issues for C code that compiles against these headers, which may occur with Ports. 2022-08-16 01:57:43 +10:00			`#include <sys/cdefs.h>`

LibC: Move waitpid() to sys/wait.h That's where POSIX says it should be. 2020-02-03 18:51:48 +03:00			`pid_t waitpid(pid_t, int* wstatus, int options);`

Kernel+LibC: Add sys$waitid(), and make sys$waitpid() wrap it sys$waitid() takes an explicit description of whether it's waiting for a single process with the given PID, all of the children, a group, etc., and returns its info as a siginfo_t. It also doesn't automatically imply WEXITED, which clears up the confusion in the kernel. 2020-02-05 19:42:43 +03:00			`int waitid(idtype_t idtype, id_t id, siginfo_t* infop, int options);`
