       NAME
             thr_setspecific - set thread-specific data

       SYNOPSIS
             cc [options] -Kthread file
             #include <thread.h>
             int thr_setspecific(thread_key_t key, void *value);

          Parameters
             key    key to which value is to be bound

             value  pointer to thread-specific data, or NULL

       DESCRIPTION
             thr_setspecific associates a thread-specific value with key.
             Different threads may bind different values to the same key.

             If the value bound to key must be updated during the lifetime
             of the thread, the caller must release the storage associated
             with the old value before a new value is bound, or the storage
             is lost.

          key Parameter
             key is a key obtained with a previous call to
             thr_keycreate(3thread).

             The effect of calling thr_setspecific with a key value not
             obtained with thr_keycreate or after key has been deleted with
             thr_keydelete is undefined.

          value Parameter
             value is typically a pointer to blocks of dynamically-
             allocated memory that have been reserved for use by the
             calling thread.  If value is NULL, the calling thread will
             give up a non-NULL reference to key.

          Return Values
             thr_setspecific returns zero for success and an error number
             for failure, as described below.

          Errors
             If any of the following conditions is detected,
             thr_setspecific returns the corresponding value:

            EINVAL   The key value is invalid.

            ENOMEM   There is not sufficient memory available to establish
                     the binding.
