PTHREAD_KEY_DELETE(3)					   BSD Library Functions Manual 				     PTHREAD_KEY_DELETE(3)

NAME

     pthread_key_delete -- delete a thread-specific data key

SYNOPSIS

     #include <pthread.h>

     int
     pthread_key_delete(pthread_key_t key);

DESCRIPTION

     The pthread_key_delete() function deletes a thread-specific data key, previously returned by pthread_key_create().  The thread-specific data
     values associated with key need not be NULL at the time that pthread_key_delete() is called.  It is the responsibility of the application to
     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 pthread_key_delete() is called.  Any attempt to use key following the call to
     pthread_key_delete() results in undefined behavior.

     The pthread_key_delete() function is callable from within destructor functions.  Destructor functions are not invoked by
     pthread_key_delete().  Any destructor function that may have been associated with key will no longer be called upon thread exit.

RETURN VALUES

     If successful, the pthread_key_delete() function will return zero.  Otherwise, an error number will be returned to indicate the error.

ERRORS

     pthread_key_delete() will fail if:

     [EINVAL]		The key value is invalid.

STANDARDS

     pthread_key_delete() conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').

NAME

       pthread_key_delete - delete thread-specific data key

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_key_delete(pthread_key_t key);

       The  pthread_key_delete() function deletes a thread-specific data key previously returned by pthread_key_create(). The thread-specific data
       values associated with key need not be  NULL at the time pthread_key_delete() is called. It is the responsibility  of  the  application	to
       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 pthread_key_delete() is called. Any attempt to use key  following  the
       call to pthread_key_delete() results in undefined behaviour.

       The   pthread_key_delete()   function  is  callable  from  within  destructor  functions.  No  destructor  functions  will  be  invoked	by
       pthread_key_delete(). Any destructor function that may have been associated with key will no longer be called upon thread exit.

       If successful, the pthread_key_delete() function returns  0. Otherwise, an error number is returned to indicate the error.

       The pthread_key_delete() function may fail if:

       EINVAL	       The key value is invalid.

       The pthread_key_delete() function will not return an error code of EINTR.
