Rich Felker	685e40bb09	syscall overhaul part two - unify public and internal syscall interface with this patch, the syscallN() functions are no longer needed; a variadic syscall() macro allows syscalls with anywhere from 0 to 6 arguments to be made with a single macro name. also, manually casting each non-integer argument with (long) is no longer necessary; the casts are hidden in the macros. some source files which depended on being able to define the old macro SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall() instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL have also been changed. x86_64 has not been tested, and may need a follow-up commit to fix any minor bugs/oversights.	15 years ago

Rich Felker	d00ff2950e	overhaul syscall interface this commit shuffles around the location of syscall definitions so that we can make a syscall() library function with both SYS_* and __NR_* style syscall names available to user applications, provides the syscall() library function, and optimizes the code that performs the actual inline syscalls in the library itself. previously on i386 when built as PIC (shared library), syscalls were incurring bus lock (lock prefix) overhead at entry and exit, due to the way the ebx register was being loaded (xchg instruction with a memory operand). now the xchg takes place between two registers. further cleanup to arch/$(ARCH)/syscall.h is planned.	15 years ago
Rich Felker	56fd65e861	some linux headers useful from user apps. i'm still not sure whether it's a good idea to include or use any of these, but i'll add them for now. it may make more sense to just add official kernel headers to the include path for compiling programs that need them.	15 years ago
Rich Felker	f5ba2bc9ca	various legacy and linux-specific stuff this commit is part of an effort to make more of busybox work out-of-the-box.	15 years ago
Rich Felker	e18b563821	implement [v]swprintf	15 years ago
Rich Felker	047e434ef5	implement robust mutexes some of this code should be cleaned up, e.g. using macros for some of the bit flags, masks, etc. nonetheless, the code is believed to be working and correct at this point.	15 years ago
Rich Felker	b446c55b6f	remove some old cruft from sys/types.h	15 years ago
Rich Felker	d8d19f4d46	pthread.h needs clockid_t actually it gets this from time.h if _POSIX_C_SOURCE or any other feature test macros are defined, but it breaks if they're not.	15 years ago
Rich Felker	f1821fce81	missing const in some pthread_attr_* prototypes	15 years ago
Rich Felker	81af503610	fix sem_open and sem_close to obey posix semantics multiple opens of the same named semaphore must return the same pointer, and only the last close can unmap it. thus the ugly global state keeping track of mappings. the maximum number of distinct named semaphores that can be opened is limited sufficiently small that the linear searches take trivial time, especially compared to the syscall overhead of these functions.	15 years ago

Rich Felker	ac12eb91bd	fcntl.h should make availabel the mode constants from sys/stat.h also remove some legacy nonsense that crept in.	15 years ago

Rich Felker	eee150f39c	make real symbols for the legacy (nonstandardized) utmp functions this is needed in the long term for ABI compatibility anyway, and in the immediate, it helps with building broken programs like GNU screen that try to prototype the functions themselves rather than using the header.	15 years ago
Rich Felker	d6a1e0c79e	resolve some header namespace non-issues after re-reading 2.2.2 of POSIX 2008, all of these are in the correct reserved namespaces and do not need protection.	15 years ago
Rich Felker	855df698c4	move the GNU siginfo renaming so it doesn't lead to mismatching names	15 years ago
Rich Felker	2b43ef8fc7	make sys/param.h not depend on PATH_MAX and NAME_MAX this is a nonstandard header used only by backwards programs, but for some reason it's extremely popular. the recent namespace cleanup fixes broke it, because PATH_MAX and NAME_MAX will not be defined unless an approriate feature test macro has been defined. moreover, it's too late to just #define _GNU_SOURCE in param.h, since limits.h may have already been included. let's just hard-code standard values and be done with it.	15 years ago

Rich Felker	ad2fe25041	support the ugly and deprecated ucontext and sigcontext header stuff... only the structures, not the functions from ucontext.h, are supported at this point. the main goal of this commit is to make modern gcc with dwarf2 unwinding build without errors. honestly, it probably doesn't matter how we define these as long as they have members with the right names to prevent errors while compiling libgcc. the only time they will be used is for propagating exceptions across signal-handler boundaries, which invokes undefined behavior anyway. but as-is, they're probably correct and may be useful to various low-level applications dealing with virtualization, jit code generation, and so on...	15 years ago
Rich Felker	e9417fffb3	add pthread_atfork interface note that this presently does not handle consistency of the libc's own global state during forking. as per POSIX 2008, if the parent process was threaded, the child process may only call async-signal-safe functions until one of the exec-family functions is called, so the current behavior is believed to be conformant even if non-ideal. it may be improved at some later time.	15 years ago
Rich Felker	d5ca067c7b	add portable lchown (trivial to support and a few ancient things want it..)	15 years ago
Rich Felker	e882756311	reorganize pthread data structures and move the definitions to alltypes.h this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.	15 years ago
Rich Felker	798a12ecc4	ucontext is no longer in the standard, so use gnu-friendly struct name note that this header is still bogus and needs a lot of work and factoring into arch-dependent parts...	15 years ago
