Invoke the system_profiler tool and parse its output; use something like "system_profiler -xml SPHardwareDataType".

i am unable to find any API called "system_profiler()" that I can call from my C++ (carbon) program. 


Something like the following?

#include <CoreFoundation/CoreFoundation.h>
#include <stdio.h>

CFPropertyListRef system_profiler()
{
	FILE *fp = popen( "system_profiler -xml", "r" );
	CFMutableDataRef dataRef = CFDataCreateMutable( NULL, 0 );
	CFPropertyListRef listRef;
	char buf[1024];
	size_t size;

while( (size = fread(buf, sizeof(buf), 1, fp)) )
CFDataAppendBytes( dataRef, (const UInt8*)buf, size );
pclose( fp );
listRef = CFPropertyListCreateFromXMLData( NULL, dataRef, kCFPropertyListImmutable, NULL );
CFRelease( dataRef );
return listRef;
}

Perhaps add some error checking on the return of popen(); maybe an ferror() before pclose().
