     #include <pthread.h>

     void *

DESCRIPTION    [Toc]    [Back]

     The pthread_getspecific() function returns the value currently bound to
     the specified key on behalf of the calling thread.

     The effect of calling pthread_getspecific() with a key value not obtained
     from pthread_key_create() or after key has been deleted with
     pthread_key_delete() is undefined.

     The pthread_getspecific() function may be called from a thread-specific
     data destructor function.

RETURN VALUES    [Toc]    [Back]

     The pthread_getspecific() function will return the thread-specific data
     value associated with the given key.  If no thread-specific data value is
     associated with key, then the value NULL is returned.

ERRORS    [Toc]    [Back]

     None.
