QNX Neutrino Core OS 6.3.2

New entries

posix_typed_mem_get_info(), posix_typed_mem_open(): New functions for POSIX support of memory-mapping.
pthread_getname_np(), pthread_setname_np(): The pthread_getname_np() function retrieves the name of a thread. The pthread_setname_np() function names a thread in your application.
pthread_attr_getstackprealloc(), pthread_attr_setstackprealloc(): Get and set the memory to preallocate for a MAP_LAZY stack.
munmap_flags(): Unmap previously mapped addresses, exercising more control
SchedCtl(): Control the adaptive partitioning scheduler
SIGEV_CLEAR_CRITICAL(): In adaptive partitioning, make a thread run as noncritical. See sigevent.
SIGEV_GET_TYPE(): Determine the type of a sigevent event. See sigevent.
SIGEV_MAKE_CRITICAL(): In adaptive partitioning, make a thread run as critical. See sigevent.

Changed content

If you're using adaptive partitioning and you set _NTO_CHF_FIXED_PRIORITY, the receiving thread won't run in the sending thread's partition.

getrlimit(), getrlimit64(), setrlimit(), setrlimit64()

Added the following resources:

RLIMIT_MEMLOCK
RLIMIT_NPROC
RLIMIT_NTHR
RLIMIT_OFILE
RLIMIT_RSS

iofunc_open_default()

The documentation now describes the extra argument.

mlock(), mlockall(), munlock()

The documentation now describes the POSIX support for memory mapping.

mmap()

The documentation now includes a new MAP_NOINIT flag.

msync()

The documentation now describes new MS_CACHE_ONLY flag.

posix_mem_offset(), posix_mem_offset64()

The documentation now describes the POSIX support for memory mapping.

sigevent

In the future, the library might use hidden bits in the sigev_notify member of the sigevent structure. Don't compare this member directly to values such as SIGEV_PULSE; use the SIGEV_GET_TYPE() macro.

spawn()

The documentation now describes the SPAWN_EXPLICIT_CPU flag and the runmask member of the inheritance structure.

ThreadCtl()

The documentation now contains the following commands:

_NTO_TCTL_NAME
_NTO_TCTL_ONE_THREAD_HOLD
_NTO_TCTL_ONE_THREAD_CONT
_NTO_TCTL_RUNMASK_GET_AND_SET
_NTO_TCTL_RUNMASK_GET_AND_SET_INHERIT
