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

  0	    Successful completion.

  [EINVAL]  The value for key is invalid.




ERRORS
  None
