Hi,
It is said that QNX provides one synchronization way called, aotmic
operation. However, I don’t find the description of the concept of atomic
operations and the way of how to use it.
Anybody knows it?
Thanks,
Belinda

Check out the atomic_add() (and friends) function in the library reference
manual.

QNX also provides a bunch of other synchronisation methods, including
semaphores, mutexes, condition variables, reader/writer locks, and
more.

atomic_* are a family of low-level functions for doing “atomic” that
is unpreemptable and uninterruptable operations on simple data types,
look in the table of contents in the library reference under the letter
a for a list of them.
