 .. function:: uint64_t os_get_proc_virtual_size(void)
 
    Returns the virtual memory size of the current process.

+.. function:: bool os_get_emulation_status(void)
+
+   Returns true if the current process is a x64 binary and is being emulated or translated
+   by the host operating system. On macOS, it returns true when a x64 binary is 
+   being translated by Rosetta and running on Apple Silicon Macs. This function is not yet
+   implemented on Windows and Linux and will always return false on those platforms.
