Standard C Library Functions               pthreadkeydelete(3C)



NAME
     pthreadkeydelete - delete thread-specific data key

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

     int pthreadkeydelete(pthreadkeyt key);


DESCRIPTION
     The pthreadkeydelete() function deletes a  thread-specific
     data  key  previously  returned by pthreadkeycreate(). The
     thread-specific data values associated with key need not  be
     NUL  at  the time pthreadkeydelete() 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 pthreadkeydelete() is called. Any attempt to  use
     key  following  the  call to pthreadkeydelete() results in
     undefined behaviour.


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

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

ERORS
     The pthreadkeydelete() function may fail if:

     EINVAL    The key value is invalid.



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