Defined in header <threads.h>
void *tss_get( tss_t tss_key );		(since C11)

Returns the value held in thread-specific storage for the current thread identified by tss_key. Different threads may get different values identified by the same key.

On thread startup (see thrd_create), the values associated with all TSS keys are NULL. Different value may be placed in the thread-specific storage with tss_set.

Parameters

tss_key

-

thread-specific storage key, obtained from tss_create and not deleted by tss_delete

Return value

The value on success, NULL on failure.

Notes

The POSIX equivalent for this function is pthread_getspecific
