How can I determine the amount of physical memory (RAM) available?

[nexus6]

The amount of RAM installed on a machine...

I see that I can get this info in the DevStudio product...

http://helpnet.installshield.com/robo/projects/HelpLibDevStudio9/IHelpPropReference.htm#Hardware

How can I get it in InstallShield MP 11.5?

Or, if there is no automatic wizardly way, can somebody tell me if/how this information can be obtained from Java?

Thanks!

Java cannot make this call. You'll need to make a JNI call to the. Here are the calls you'd need to make in C to get system memory in Windows and UNIX.

#ifdef WIN32
	MEMORYSTATUS ms;

	GlobalMemoryStatus(&ms);

	//Debug 1024000L 1048576L
	//printf("Total physical: %lu bytes (%luMB)\n", ms.dwTotalPhys, ms.dwTotalPhys / 1048576L);
	return (ms.dwTotalPhys / 1048576L);
#endif

	/**
	 * sysconf(_SC_PHYS_PAGES) returns a long containing the number of memory pages; 
	 * you have then to multiply by sysconf(_SC_PAGESIZE), the number of bytes 
	 * per memory page (that varies depending from the hardware you have).  
	 * And to divide by 1024*1024 if you need units of Megabytes :-)
	 */
#ifndef WIN32
	long n_phys, s_phys;
	n_phys = (sysconf (_SC_PHYS_PAGES)/1024) * (sysconf (_SC_PAGESIZE)/1024);
	return n_phys;	
#endif

Thanks, I appreciate the post!
