Description

This routine deletes a data key key previously returned by tis_key_create. 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 call. Do not attempt to use the key after calling this routine, since this results in unpredictable behavior.

No destructor functions are invoked by this routine. Any destructor functions that may have been associated with key, shall no longer be called upon thread exit. tis_key_delete can be called from within destructor functions.

Return Values

If an error condition occurs, this routine returns an integer indicating the type of error. Possible return values are as follows:
