tis_key_delete(3)					     Library Functions Manual						 tis_key_delete(3)

NAME

       tis_key_delete - Deletes the specified thread-specific data key.

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <tis.h>

       int   tis_key_delete(
			      pthread_key_t   key);

STANDARDS

       None

PARAMETERS

       Thread-specific data key to be deleted.

DESCRIPTION

       This  routine deletes a thread-specific data key key previously returned by a call to the tis_key_create(3) routine.  The data values asso-
       ciated 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 the deleted key or associated data.	This cleanup can be done before or after this rou-
       tine 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

       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

       None
