Invoke the system_profiler tool and parse its output; use something

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().
