Function: initEnumHardware
Date: 10/9
Implementor(s): jdt
Library: init
Description:
Calls a user supplied function on an initialized InitDeviceInfo
structure for each device in the system. Calls a user supplied
callback repeatedly for each device in the system. The callback
can stop the enumeration cycle by return a value of FXTRUE.
Arguments:
cb - callback function of type INitHWEnumCallback which is called on
an initialzied InitDeviceInfo structure
Return:
none
