Author: bonefish
Date: 2011-05-19 18:54:59 +0200 (Thu, 19 May 2011)
New Revision: 41583
Changeset: https://dev.haiku-os.org/changeset/41583
Added:
haiku/branches/developer/bonefish/signals/headers/private/system/signal_defs.h
Modified:
haiku/branches/developer/bonefish/signals/headers/posix/unistd.h
haiku/branches/developer/bonefish/signals/src/system/libroot/posix/unistd/conf.c
Log:
* Added _POSIX_SIGQUEUE_MAX and _SC_SIGQUEUE_MAX macros to <unistd.h>. Handle
the latter in sysconf().
* Added new private header/private/system/signal_defs.h defining
MAX_QUEUED_SIGNALS, the actual signal queuing limit.
Modified: haiku/branches/developer/bonefish/signals/headers/posix/unistd.h
