Synopsis
timerread
Description
This program demonstrates how to use the timer device to read the current
system time.
The program does the following:
- Opens the timer device
- Creates an IOReq
- Initializes an IOInfo structure
- Calls
DoIO() to perform the read operation
- Prints out the current time
- Cleans up
Note that Portfolio provides convenience routines to make using the timer
device easier. For example, CreateTimerIOReq() and
DeleteTimerIOReq(). This example intends to show how in
general one can communicate with devices in the Portfolio environment. For
more information on the timer convenience routines, see the timer device
documentation.
