pthread_setspecific

pthread_getspecific(3T) 												   pthread_getspecific(3T)

NAME

       pthread_getspecific(), pthread_setspecific() - get or set the thread-specific data associated with a key

SYNOPSIS

PARAMETERS

	      key	Thread-specific data key whose value for the calling thread is to be set or retrieved.

	      value	Value to be assigned to the thread-specific data key for the calling thread.

DESCRIPTION

       The  function  returns the thread-specific data value associated with key for the calling thread.  If no value has been associated with key
       for the calling thread, NULL is returned.

       The function associates the thread-specific data value with key.  Each thread may bind a different value to key.  These values are  usually
       pointers to memory dynamically allocated by the calling thread.

       key  must be a valid thread-specific data key created by calling If key is not a valid thread-specific data key, undefined behavior results
       when calling these functions.

       These functions may be called from a thread-specific data destructor function. However, calling from a destructor may result in lost  stor-
       age.

RETURN VALUE

       The  function  returns  the  thread-specific data value associated with key.  If no thread-specific data value is currently associated with
       key, the value NULL is returned.

       If successful, returns zero. Otherwise, an error number is returned to indicate the error (the variable is not set).

ERRORS

       No errors are returned by the function.

       If any of the following occur, the function returns the corresponding error number:

	      [ENOMEM]	     There is insufficient memory available in which to associate value with key.

       For each of the following conditions, if the condition is detected, the function returns the corresponding error number:

	      [EINVAL]	     key is an invalid thread-specific data key.
