Basic Types
Defines basic data types and macros for the platform to use.
This module defines the basic data types and macros for the platform, so that it is easier to port the software to other hardware platform. The software of the platform should use the data types or macros defined in this module, rather than these C primitive types directly.

Do not compare it with VM_RESULT directly, i.e. DO NOT USE if(VM_FAIL==xxxx()) to determine a failure or not. Instead, use if(VM_IS_FAILED(xxx()). | |

Use this macro to determine if a VM_RESULT is a success or not. | |
|
Do not compare it with VM_RESULT directly. | |
|
General result type for LinkIt SDK API. Must be used with VM_IS_SUCCEEDED() and VM_IS_FAILED() to confirm sucess or not. Do not compare with VM_SUCESS and VM_FAIL directly. | |
