Demonstrates how to use the timer device to wait for an amount of time specified on the command-line.

timersleep <num seconds> <num microseconds>

This program demonstrates how to use the timer device to wait for a certain amount of time.

The program does the following:

• Parses the command-line arguments
• Opens the timer device
• Creates an IOReq
• Initializes an IOInfo structure
• Calls DoIO() to perform the wait operation
• Cleans up

Note that Portfolio provides convenience routines to make using the timer device easier. For example, CreateTimerIOReq(), DeleteTimerIOReq(), and WaitTime(). 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.

• num seconds Number of seconds to wait.

• num microseconds Number of microseconds to wait.
