* Remove single-use macros obfuscating malloc(9) and free(9) calls.Konstantin Belousov2015-08-301-3/+0

* In order to maximize the re-usability of kernel code in user space thisKip Macy2011-09-161-1/+1
| | | | | | | | | | | | | | | | patch modifies makesyscalls.sh to prefix all of the non-compatibility calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel entry points and all places in the code that use them. It also fixes an additional name space collision between the kernel function psignal and the libc function of the same name by renaming the kernel psignal kern_psignal(). By introducing this change now we will ease future MFCs that change syscalls. Reviewed by: rwatson Approved by: re (bz) Notes: svn path=/head/; revision=225617

* Rework the sysconf(3) interaction with aio:Alfred Perlstein2002-11-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | sysconf.c: Use 'break' rather than 'goto yesno' in sysconf.c so that we report a '0' return value from the kernel sysctl. vfs_aio.c: Make aio reset its configuration parameters to -1 after unloading instead of 0. posix4_mib.c: Initialize the aio configuration parameters to -1 to indicate that it is not loaded. Add a facility (p31b_iscfg()) to determine if a posix4 facility has been initialized to avoid having to re-order the SYSINITs. Use p31b_iscfg() to determine if aio has had a chance to run yet which is likely if it is compiled into the kernel and avoid spamming its values. Introduce a macro P31B_VALID() instead of doing the same comparison over and over. posix4.h: Prototype p31b_iscfg(). Notes: svn path=/head/; revision=106998

* Add the rest of the kernel support for the sem_ API in kern/uipc_sem.c.Alfred Perlstein2002-09-191-0/+1
| | | | | | | | | | | | | Option 'P1003_1B_SEMAPHORES' to compile them in, or load the "sem" module to activate them. Have kern/makesyscalls.sh emit an include for sys/_semaphore.h into sysproto.h to pull in the typedef for semid_t. Add the syscalls to the syscall table as module stubs.

* KSE Milestone 2Julian Elischer2001-09-121-8/+8
| | | | | | | | | | | | | | | | | Note ALL MODULES MUST BE RECOMPILED make the kernel aware that there are smaller units of scheduling than the process. (but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process. Sorry john!

| | | | | | | | | | | | | | | | | | | | | | | | | | Changes to support building with _POSIX_SOURCE set to 199309L: 1. Add sys/_posix.h to handle those preprocessor defs that POSIX says have effects when defined before including any header files; 2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE 3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now defined in POSIX. These show up when: _POSIX_SOURCE and _POSIX_C_SOURCE are not set or _POSIX_C_SOURCE is set >= 199309L and vanish when: _POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L. 4. Explain these in man 9 posix4; 5. Include _posix.h and conditionalize on new feature test. Notes: svn path=/head/; revision=34319
