NAME
       pthread_key_delete - Deletes a thread-specific data key.

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS
       #include <pthread.h>

       int   pthread_key_delete(
			      pthread_key_t   key);

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS
       Context key to be deleted.

DESCRIPTION
       This  routine  deletes  the  thread-specific  data  key	specified  by  the  key  argument,  which  must  have  been previously returned by
       pthread_key_create(3).

       The thread-specific 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 thread-specific data in any
       threads.  This cleanup can be done either before or after this routine is called.

       Do not attempt to use the key after calling this routine; this results in unpredictable behavior.

       No destructor functions are invoked by this routine.  Any destructor functions that may have been associated with key shall  no	longer	be
       called upon thread exit.  pthread_key_delete(3) 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 key value is an invalid argument.

ERRORS
       None
