Your message handler will have access to a structure that contains the full entry, the new value, its length, and three optional arguments. The change-notification handlers should be used to cache initialization entries locally for faster access or to perform certain tasks that are required if a value changes. For example, if a constant connection to a certain host is required by a module and someone changes the hostname, automatically terminate the old connection and attempt a new one. Access to initialization entries can also be handled with the macros shown in Table 9.17. Returns the current value of entry name as string.
Further access requires duplication to local memory.
Returns the original value of entry name as string. Further access requires duplication to local memory. Zend Technologies Ltd. All rights reserved.
