# UART Select Example
|
|
|
|
The UART select example is for demonstrating the use of `select()` for
|
|
synchronous I/O multiplexing on the UART interface. The example waits for a
|
|
character from UART using `select()` until a blocking read without delay or a
|
|
successful non-blocking read is possible.
|
|
|
|
Please note that the same result can be achieved by using `uart_read_bytes()`
|
|
but the use of `select()` allows to use it together with other virtual
|
|
file system (VFS) drivers, e.g. LWIP sockets. For a more comprehensive example
|
|
please refer to `system/select`.
