# go-libpcsclite
|
||
|
|
|
||
|
|
A golang implementation of the [libpcpsclite](http://github.com/LudovicRousseau/PCSC) client. It connects to the `pcscd` daemon over sockets.
|
||
|
|
|
||
|
|
## Purpose
|
||
|
|
|
||
|
|
The goal is for major open source projects to distribute a single binary that doesn't depend on `libpcsclite`. It provides an extra function `CheckPCSCDaemon` that will tell the user if `pcscd` is running.
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
```golang
|
||
|
|
func main() {
|
||
|
|
client, err := EstablishContext(2)
|
||
|
|
if err != nil {
|
||
|
|
fmt.Printf("Error establishing context: %v\n", err)
|
||
|
|
os.Exit(1)
|
||
|
|
}
|
||
|
|
|
||
|
|
_, err = client.ListReaders()
|
||
|
|
if err != nil {
|
||
|
|
fmt.Printf("Error getting the list of readers: %v\n", err)
|
||
|
|
os.Exit(1)
|
||
|
|
}
|
||
|
|
|
||
|
|
card, err := client.Connect(client.readerStateDescriptors[0].Name, ShareShared, ProtocolT0|ProtocolT1)
|
||
|
|
if err != nil {
|
||
|
|
fmt.Printf("Error connecting: %v\n", err)
|
||
|
|
os.Exit(1)
|
||
|
|
}
|
||
|
|
|
||
|
|
resp, _, err := card.Transmit([]byte{0, 0xa4, 4, 0, 0xA0, 0, 0, 8, 4, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0})
|
||
|
|
|
||
|
|
card.Disconnect(LeaveCard)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
