PROXY:shared_table_delete()

Deletes an entry specified by a key from the shared table. If the key does not exist, the function will do nothing. If there is more than one process attached to the data entry, this function only detaches the calling process.

This function will fail if the table has not been created yet; it will not trigger the creation of a new table.

Returns Boolean true if successful, otherwise, returns Boolean false.
