ConservativeGC.realloc

void *realloc realloc(void * p, size_t size, uint bits = 0, const TypeInfo ti = null) nothrow

Request that the GC reallocate a block of memory, attempting to adjust the size in place if possible. If size is 0, the memory will be freed.

If p was not allocated by the GC, points inside a block, or is null, no action will be taken.

`p`	A pointer to the root of a valid memory block or to null.
`size`	The desired allocation size in bytes.
`bits`	A bitmask of the attributes to set on this block. APPENDABLE and FINALIZE are not allowed for realloc.
`ti`	TypeInfo to describe the memory.

A reference to the allocated memory on success or null if size is

zero.

OutOfMemoryError on allocation failure.
