Detailed Description
template<class CHAR>
class ACE_Obstack_T< CHAR >
Define a simple "mark and release" memory allocation utility.
The implementation is similar to the GNU obstack utility, which is used extensively in the GCC compiler.

Copy the data into the current Obchunk and freeze the current block. Return the starting address of the current building block, 0 if error occurs. len specify the string length, not the actually data size.
Dump the state of an object.
Freeze the current building block by null terminating it. Return the starting address of the current building block, 0 if error occurs.
Inserting a new CHAR c into the current building block without freezing (null terminating) the block. This function will create new chunk by checking the boundary of current Obchunk. Return the location c gets inserted to, or 0 if error.
Inserting a new CHAR c into the current building block without freezing (null terminating) the block and without checking for out-of-bound error.
Return the maximum length or size of a string that can be put into this Obstack. size = length * sizeof (CHAR).
- Deprecated:
- No need to use this function as you can put objects of arbitrary lengths into the obstack now.
"Release" the entire stack of Obchunks, putting it back on the free list.
Request Obstack to prepare a block at least len long for building a new string. Return -1 if fail, 0 if success.
"Unwind" the stack. If obj is a null pointer, everything allocated in the stack is released. Otherwise, obj must be an address of an object allocated in the stack. In this case, obj is released along with everthing allocated in the Obstack since obj.
