Use the -l c option to qcc to link against this library. This library is usually included automatically.

The pthread_setcancelstate() function sets the calling thread's cancellation state to state and returns the previous cancellation state in oldstate.

The cancellation state can have the following values:

Cancellation requests are held pending.

Cancellation requests may be acted on according to the cancellation type; see pthread_setcanceltype().

The default cancellation state for a thread is PTHREAD_CANCEL_ENABLE.

You can set this attribute (in a non-POSIX way) before creating the thread; for more information, see " BlackBerry 10 OS extensions," in the documentation for pthread_create().

Returns:

EOK
Success.
EINVAL
The cancellation state specified by state is invalid.
