IEEE Std 1003.1c-1995, POSIX System Application Program Interface
PARAMETERS
The context key identifies the thread-specific data to be obtained.
DESCRIPTION
This routine obtains the thread-specific data associated with the spec‐
ified key for the current thread. Obtain this key by calling the
pthread_key_create(3) routine. This routine returns the value currently
bound to the specified key on behalf of the calling thread.
This routine may be called from a thread-specific data destructor func‐
tion.
RETURN VALUES
No errors are returned. This routine returns the thread-specific data
value associated with the specified key argument. If no thread-spe‐
cific data value is associated with key, or if key is not defined, then
this routine returns a NULL value.
