Function Documentation

tss_async_signal_safe_create()

int tss_async_signal_safe_create ( tss_async_signal_safe *  val, const struct tss_async_signal_safe_attr *  attr  )

extern

Create an async signal safe thread local instance.

tss_async_signal_safe_destroy()

int tss_async_signal_safe_destroy ( tss_async_signal_safe  val )

extern

Destroy an async signal safe thread local instance.

tss_async_signal_safe_get()

void * tss_async_signal_safe_get ( tss_async_signal_safe  val )

extern

THREADSAFE ASYNC-SIGNAL-SAFE Get the thread local value for the current thread.

tss_async_signal_safe_thread_init()

int tss_async_signal_safe_thread_init ( tss_async_signal_safe  val )

extern

THREADSAFE Initialise an async signal safe thread local instance for a specific thread.

The initialisation and registration of a thread local state for a specific thread is not async signal safe, and so must be manually performed by each thread before use of an async signal safe thread local instance. Call this function somewhere near the beginning of your thread instance.

It is safe to call this functions many times in a thread.
