tis_key_delete(3)


NAME

  tis_key_delete - Deletes the specified thread-specific data key


SYNOPSIS

  #include <tis.h>

  int tis_key_delete(
	  pthread_key_t key );


LIBRARY

  Standard C Library (libc.so, libc.a)


STANDARDS

  None


PARAMETERS

  key Thread-specific data key to be deleted.


DESCRIPTION

  This routine deletes a thread-specific data key key previously returned by
  a call to the tis_key_create(3) routine. The 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 data. This cleanup can
  be done before or after this routine is called.

  Attempting to use the thread-specific data key key after calling this
  routine results in unpredictable behavior.

  No destructor functions are invoked by this routine. Any destructor
  functions that may have been associated with key will no longer be called
  upon thread exit.

  This routine 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:

  0   Successful completion.

  [EINVAL]
      The value for key is invalid.


ERRORS

  None
