- *
- * The talloc_free() function frees a piece of talloc memory, and all its
- * children. You can call talloc_free() on any pointer returned by
- * talloc().
- *
- * The return value of talloc_free() indicates success or failure, with 0
- * returned for success and -1 for failure. A possible failure condition
- * is if the pointer had a destructor attached to it and the destructor
- * returned -1. See talloc_set_destructor() for details on
- * destructors. Likewise, if "ptr" is NULL, then the function will make
- * no modifications and return -1.
- *
- * From version 2.0 and onwards, as a special case, talloc_free() is
- * refused on pointers that have more than one parent associated, as talloc
- * would have no way of knowing which parent should be removed. This is
- * different from older versions in the sense that always the reference to
- * the most recently established parent has been destroyed. Hence to free a
- * pointer that has more than one parent please use talloc_unlink().
- *
- * To help you find problems in your code caused by this behaviour, if
- * you do try and free a pointer with more than one parent then the
- * talloc logging function will be called to give output like this:

- * pointer is about to be released. The destructor receives the pointer as an
- * argument, and should return 0 for success and -1 for failure.
- *
- * The destructor can do anything it wants to, including freeing other pieces

- *
- * You can only place one destructor on a pointer. If you need more than one

- * @brief Allocate a talloc pool.
- *
- * A talloc pool is a pure optimization for specific situations. In the
- * release process for Samba 3.2 we found out that we had become considerably
- * slower than Samba 3.0 was. Profiling showed that malloc(3) was a large CPU
- * consumer in benchmarks. For Samba 3.2 we have internally converted many
- * static buffers to dynamically allocated ones, so malloc(3) being beaten
- * more was no surprise. But it made us slower.
- *
- * talloc_pool() is an optimization to call malloc(3) a lot less for the use
- * pattern Samba has: The SMB protocol is mainly a request/response protocol
- * where we have to allocate a certain amount of memory per request and free
- * that after the SMB reply is sent to the client.
- *
- * talloc_pool() creates a talloc chunk that you can use as a talloc parent
- * exactly as you would use any other ::TALLOC_CTX. The difference is that
- * when you talloc a child of this pool, no malloc(3) is done. Instead, talloc
- * just increments a pointer inside the talloc_pool. This also works
- * recursively. If you use the child of the talloc pool as a parent for
- * grand-children, their memory is also taken from the talloc pool.
- *
- * If you talloc_free() children of a talloc pool, the memory is not given
- * back to the system. Instead, free(3) is only called if the talloc_pool()
- * itself is released with talloc_free().
- *
- * The downside of a talloc pool is that if you talloc_move() a child of a
- * talloc pool to a talloc parent outside the pool, the whole pool memory is
- * not free(3)'ed until that moved chunk is also talloc_free()ed.
