max_malloc_size()

mp_integer configt::max_malloc_size

(

)

const

The maximum allocation size is determined by the number of bits that are left in the pointer of width ansi_c.pointer_width.

The allocation size cannot exceed the number represented by the (signed) offset, otherwise it would not be possible to store a pointer into a valid bit of memory. Therefore, the max allocation size is 2^(offset_bits - 1), where the offset bits is the number of bits left in the pointer after the object bits.

The offset must be signed, as a pointer can point to the end of the memory block, and needs to be able to point back to the start.

Returns

The size in bytes of the maximum allocation supported.
