Methods

Method	Description
DMemBuffer(Type *, ptrdiff_t, bool)	Attach an existing buffer, optionally taking ownership
DMemBuffer(ptrdiff_t)	Allocate a buffer, specifying the number of items
DMemBuffer(void *, ptrdiff_t)	Attach an existing buffer
allocate	Allocate a specified number of the items
attach	Attach an existing buffer, optionally taking ownership
detachBuffer	Detach the buffer, but do not delete it, and return a pointer to the start of the buffer
extend	Try to ensure that the buffer is at least of a specified size, extending the buffer if necessary, and throw std::bad_alloc if the buffer cannot be extended
getBuffer	Get start of buffer
getMaxCount	Get buffer size
store	Store data in buffer
tryExtend	Try to ensure that the buffer is at least of a specified size, extending the buffer if necessary, and return false if the buffer cannot be allocated

Remarks

The items must be simple types such as char or wchar_t that can be copied with memmove. For internal use by the other classes.
