kern_return_t always returns KERN_INVALID_ARGUMENT (number 4) for some reason.

Also, no data is being set.

I have the the following code:

- (void)test

{

pid_t thePid = 47743;

mach_port_t currentTask;

//vm_region_basic_info_data_t

vm_region_basic_info_data_t currentInfo;

mach_msg_type_number_t currentInfoSize = VM_REGION_BASIC_INFO_COUNT;

mach_vm_size_t currentBlockSize = 0;

mach_vm_address_t currentAddress = 0;

mach_port_t currentObject = MACH_PORT_NULL;

kern_return_t kReturn;

kReturn = task_for_pid (mach_task_self(), thePid, &currentTask);

if (kReturn == KERN_SUCCESS)

{

kReturn = mach_vm_region(currentTask,&currentAddress,&currentBlockSize,VM_REGION_BASIC_INFO,(vm_region_info_t)&currentInfo,&currentInfoSize,&currentObject);

NSRange dataRange = NSMakeRange(currentAddress, currentBlockSize);

printf("The kernal returns %i\n",kReturn);

printf("Range: %s\n",[NSStringFromRange(dataRange) UTF8String]);

}

currentBlockSize remains zero as well so the address range is {0,0}

In an additional note, the linker refuses to like vm_region and declares it "an undefined symbol. Did you mean: mach_vm_region?"

I'd really love any help at this point.
