* goto break; != break;Doug Barton2002-11-171-3/+3
| | | | | | | | | I've no idea if this is the right behavior for the library, but this at least fixes the build, and matches what seems to be alfred's intent in the commit message for 1.19. Notes: svn path=/head/; revision=107000
* Rework the sysconf(3) interaction with aio:Alfred Perlstein2002-11-171-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Provide more correct default values for sysconf(3) reporting of the AIOAlfred Perlstein2002-11-161-0/+3
| | | | | | | | | | | | | | | | subsystems capabilities: _SC_AIO_LISTIO_MAX returns the default of _POSIX_AIO_LISTIO_MAX _SC_AIO_MAX returns the default _POSIX_AIO_MAX _SC_AIO_PRIO_DELTA_MAX returns the default of 0 Without these adjustments the values returned are -1 even when the aio side of the kernel returns '0' for them which is incorrect.

* Update limits and configuration parameters for 1003.1/TC1/D6.Garrett Wollman2002-10-271-1/+23
| | | | | | | | | | | | | | Implement new sysconf keys. Change the implenentation of _SC_ASYNCHRONOUS_IO in preparation for the next set of changes. Move some limits which had been in <sys/syslimits.h> to <limits.h> where they belong. They had only ever been in syslimits.h to provide for the kernel implementation of the CTL_USER MIB branch, which went away with newsysctl years ago. (There is a #error in <sys/syslimits.h> which I will downgrade in the next commit.) Notes: svn path=/head/; revision=106055
* Initiate deorbit burn sequence for sysctl CTL_USER MIB branch.Garrett Wollman2002-09-211-105/+351
| | | | | | | | | | | | | | | | Use the correct constants directly from sysconf() rather than calling sysctl() to tell us the (still compiled-in) value. Leave the CTL_POSIX1B stuff alone for now (but I'd like to see this replaced with a single structure returning all of the relevant information). Implement all of the keys from 1003.1-2001 that we can. Ensure that the build will break if someone redefines an option constant to zero without implementing the necessary presence-detection logic here. (4 of 5) Notes: svn path=/head/; revision=103730

| | | | | | | | | | | | | | | | | | | | | | | | | | 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
