Typedef Documentation

FixedSizeAllocator

typedef FixedSizeAllocator FixedSizeAllocator

This is a fixed size allocator implementation for the abstract interface class AllocatorIntf.

The FixedSizeAllocator takes a buffer and splits the buffer up into equally sized chunks. Allocating memory larger than the chunk size or using realloc results in an error; i.e., NULL returned. One can allocate a smaller size than the chunk size, but the size will be adjusted to the chunk size.

Function Documentation

baRealloc()

void * baRealloc	(	void *	p,
		size_t	size
	)

Returns pointer to newly-allocated space for an object of size "size", initialized, to minimum of old and new sizes, to existing contents of p (if non-null), or NULL on error.

On success, old object deallocated; otherwise unchanged.
