# Synchronous I/O multiplexing example
|
|
|
|
|
|
|
|
|
|
The example demonstrates the use of synchronous I/O multiplexing by the select()
|
|
|
|
|
function with UART and socket file descriptors. The example starts three tasks:
|
|
|
|
|
1. The first task writes periodically to the UART1 file descriptor.
|
|
|
|
|
2. The second task writes periodically to the socket descriptor.
|
|
|
|
|
3. Both UART1 and the socket are configured to act as loopbacks. The third
|
|
|
|
|
task detects by the use of select() whether it is possible to read from
|
|
|
|
|
UART1 or the socket, and receives the sent messages from the other tasks.
