Standard C Library Functions               pthread_key_delete(3C)



NAME
     pthread_key_delete - delete thread-specific data key

SYNOPSIS
     cc -mt [ flag... ] file... -lpthread [ library... ]
     #include 

     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 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.

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

ERRORS
     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.
