# `memory_map_get_total_memory_size(boot_info*)` - function (uint64_t)
Calculates the total amount of memory available, by iterating over the memory map.
The size is stored in a static variable, so no matter how often you call this function, the size will only be calculated once.
The total amount of memory is returned in bytes.
