why don't you look in the wonderful Apple's doc, as everybody seems to
think it is ?
anyway here is a code sample I use:
NSString * ucat = getSysCtlString(CTL_HW, HW_MODEL); // use
sysctl() with this constant
if([ucat hasPrefix:@"PowerBook"])
ret->Category = @"Laptop";
else if([ucat hasPrefix:@"RackMac"])
ret->Category = @"Server";
else
ret->Category = @"Work Station";
int cpufreq = getSysCtlInt(CTL_HW, HW_CPU_FREQ);
and
NSString * getSysCtlString(int firstName, int lastName)
{
int mib[2] = { firstName, lastName };
size_t len;
sysctl(mib, 2, NULL, &len, NULL, 0);
len ++; // there is a bug in sysctl(), obviously ...
char * buf = (char *) alloca(len+1);
sysctl(mib, 2, buf, &len, NULL, 0);
return [NSString stringWithCString:buf];
}
NSString * getLocalhost()
{
return getSysCtlString(CTL_KERN, KERN_HOSTNAME);
}
int getSysCtlInt(int firstName, int lastName)
{
int mib[2] = { firstName, lastName };
size_t len;
sysctl(mib, 2, NULL, &len, NULL, 0);
int ret;
sysctl(mib, 2, &ret, &len, NULL, 0);
return ret;
}
