       tis_key_delete  -  Deletes  the  specified thread-specific
       data key

PARAMETERS    [Toc]    [Back]

       Thread-specific data key to be deleted.

DESCRIPTION    [Toc]    [Back]

       This routine deletes a thread-specific data key key previously
 returned by a call to the tis_key_create(3) routine.
       The data values associated with key need not  be  NULL  at
       the time this routine is called. The application must free
       any application storage or perform any cleanup actions for
       data  structures  related to the deleted key or associated
       data. This cleanup can be done before or after  this  routine
 is called.

       Attempting  to  use the thread-specific data key key after
       calling this routine results in unpredictable behavior.

       No destructor functions are invoked by this  routine.  Any
       destructor  functions  that  may have been associated with
       key will no longer be called upon thread exit.

       This routine can be called from  within  destructor  functions.

RETURN VALUES    [Toc]    [Back]

       If  an  error  condition  occurs,  this routine returns an
       integer value  indicating  the  type  of  error.  Possible
       return  values are as follows: Successful completion.  The
       value for key is invalid.

ERRORS    [Toc]    [Back]

       None
