The start address of the reserved region.
This function reserves a region from the top of an arena. id specifies an arena using an arena ID. For details on arena ID see OS_InitArena(). For details on arena ID, see OS_InitArena(). size specifies the size to be reserved in bytes. alignment specifies alignment for the reserved region. After the region is reserved, the arena's upper boundary address will be changed by the size of the region that was taken. Because no downward boundary check is performed, problems will occur if a region larger than the arena is reserved.
