The PassMark SysInfo DLL SDK provides third party developers with the components needed to integrate the SysInfo DLL library into their applications. The SysInfo provides a set of APIs for retrieving system information about hardware components in a computer, including the:

• Motherboard
• BIOS
• CPU
• Memory, including RAM module SPD information
• Video card/Display devices
• Physical and Optical Drives
• Network adapters
• USB controllers and devices
• Ports (Serial/Parallel)

The SysInfo DLL also includes a SMART component (formerly released as SmartDisk DLL SDK), which exports an interface for retrieving SMART information from SMART-enabled hard disks. The SysInfo DLL API includes the following:

• Retrieve detailed CPU specifications (eg. manufacturer, speed, cache size, instruction support, multiplier, supported features) CPU information
• Retrieve detailed Memory specifications (eg. type, speed, manufacturer, manufactured date, voltage, timings) Memory information
• Retrieve the BIOS, motherboard, RAM, port, network adapter, and drive information via WMI (Windows Management Instrumentation)
• Retrieve SMBIOS information
• Retrieve video card and monitor information
• Retrieve information about all USB controllers and any attached USB device
• Export the information retrieved above into plain text or HTML format

SysInfo SMART API
The SMART component of the SysInfo DLL (formerly SmartDisk DLL) is an independent subset of the SysInfo set of APIs for collecting SMART attributes for SMART-enabled drives. Exported functions include the following:

• Retrieve a hard disk's device information (eg. geometry, model number, serial number, rotation speed, supported features) Hard Disk device information Hard Disk features
• Retrieve the SMART attributes from a device
• Maintain a history of SMART values for a device
• Predicting date and time (if available) of Threshold Exceed Condition (TEC) based on the collected data. Applications can use this to warn users that an "imminent" failure is about to occur.
• Generate a hard disk report, which includes the device information and its SMART attributes.

What does the SysInfo DLL SDK package contain?

• The library files, consisting of SysInfo.lib, SysInfo.dll and SysInfo.h
• Example projects for the following languages - C/C++, C#, Visual Basic
• A User Guide (HTML format) that defines the available functions in the DLL

To see a sample of what is possible using the SDK, see the free utility PassMark's DiskCheckup which is built using SysInfo DLL to report SMART attributes of your drives and PassMark's RAMMon which reports RAM details.
