한국투자증권 `eFriend Expert` Host DLL을 위한 Go 패키지
[](LICENSE)
### Example
This is a simple request tr and realdata. ([efx-console](https://github.com/ohkashi/efxMfc-go/blob/main/examples/efx-console/main.go))
```go
package main
import (
efx "efxmfc"
"fmt"
"os"
"syscall"
"time"
)
...
func main() {
acc_cnt := efx.GetAccountCount()
fmt.Printf("AccountCount: %d\n", acc_cnt)
for i := 0; i < acc_cnt; i++ {
acnt_no := efx.GetAccount(i)
fmt.Printf("Account[%d]: %s, %s\n", i, acnt_no, efx.GetAccountBrcode(acnt_no))
}
efx1 := efx.NewControl(100, OnRecvData, OnRecvRealData, OnRecvError)
var pwd string
fmt.Print("Enter Password: ")
fmt.Scanln(&pwd)
wait_time := time.Now()
if len(pwd) == 4 {
fmt.Printf("Encrypt: %s\n\n", efx.GetEncryptPassword(pwd))
sync_time := efx.Synchonize(efx.REQ_LIMIT_MS)
fmt.Printf("Synchonize() elapsed time: %v, sync time: %dms\n",
time.Since(wait_time), sync_time)
efx.RequestAccountBalance(efx1, efx.GetAccount(acc_cnt-1), pwd)
wait_time = time.Now()
wait_recv_data()
}
fmt.Println()
go func() {
stock_code := []string{"254120", "081000", "005930", "294090", "149950", "052670", "078940"}
for _, code := range stock_code {
sync_time := efx.Synchonize(efx.REQ_LIMIT_MS)
fmt.Printf("Synchonize() elapsed time: %v, sync time: %dms\n",
time.Since(wait_time), sync_time)
efx.SetSingleData(efx1, 0, "J")
efx.SetSingleData(efx1, 1, code)
efx.RequestData(efx1, "SCP", code)
wait_time = time.Now()
wait_recv_data()
}
var real_code string
for _, code := range stock_code {
str := code + " "
real_code += str
}
efx.RequestRealData(efx1, "SC_R", real_code)
fmt.Printf("--> RequestRealData(\"SC_R\", \"%s\")\n", real_code)
}()
//efx.Quit(0)
efx.MessageLoop()
