NAME

#include <magenta/syscalls.h>

size_t mx_system_get_physmem(void);

system_get_physmem() returns the total size of physical memory on the machine, in bytes.

system_get_physmem() returns a number in bytes.

system_get_physmem() cannot fail.

Currently the total size of physical memory cannot change during a run of the system, only at boot time. This might change in the future.
