获取录制路径 - InputRecordGetPath ​

函数简介 ​

获取本次 / 上次录制文件的绝对路径。InputRecord(START)（含自动命名）之后即可查询；STOP 落盘后路径仍有效，直到下次 START。

DLL 调用返回的字符串指针须释放（FreeStringPtr）。需要 InputSync 权限。

接口名称 ​

InputRecordGetPath

DLL调用 ​

c
long InputRecordGetPath(long instance);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
ola.InputRecord(1, "");
// ...
ola.InputRecord(0, "");
std::string path = ola.InputRecordGetPath();
csharp
using OLAPlug;

var ola = new OLAPlugServer();
ola.InputRecord(1, "");
ola.InputRecord(0, "");
string path = ola.InputRecordGetPath();
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ola.InputRecord(1, "")
ola.InputRecord(0, "")
path = ola.InputRecordGetPath()
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
ola.InputRecord(1, "");
ola.InputRecord(0, "");
String path = ola.InputRecordGetPath();
go
import "github.com/ola/olaplug/olaplug"

ola, _ := olaplug.NewOLAPlugServer("OLAPlug_x64.dll")
defer ola.ReleaseObj()
ola.InputRecord(1, "")
ola.InputRecord(0, "")
path := ola.InputRecordGetPath()
rust
use olaplug::OLAPlugServer;

let ola = OLAPlugServer::new("OLAPlug_x64.dll").unwrap();
ola.input_record(1, "");
ola.input_record(0, "");
let path = ola.input_record_get_path();
cpp

var path = ola.InputRecordGetPath();
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")

ola.InputRecord(0, "")
path = ola.InputRecordGetPath()

aardio

var ola = OLAPlugServer();
ola.InputRecord(1, "");
ola.InputRecord(0, "");
var path = ola.InputRecordGetPath();
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
ola.InputRecord(1, "");
ola.InputRecord(0, "");
文本型 path = ola.InputRecordGetPath()
cpp
#include "OLAPlugServer.h"

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
InputRecord(instance, 1, "");
InputRecord(instance, 0, "");
long ptr = InputRecordGetPath(instance);
if (ptr != 0) {
    char buffer[512] = {0};
    GetStringFromPtr(ptr, buffer, sizeof(buffer));
    FreeStringPtr(ptr);
}
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringFromPtr(long ptr, StringBuilder lpString, int size);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int FreeStringPtr(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringSize(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int InputRecord(long instance, int action, string path);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long InputRecordGetPath(long instance);

long instance = CreateCOLAPlugInterFace();
InputRecord(instance, 1, "");
InputRecord(instance, 0, "");
long ptr = InputRecordGetPath(instance);
if (ptr != 0) {
    StringBuilder sb = new StringBuilder(GetStringSize(ptr) + 1);
    GetStringFromPtr(ptr, sb, sb.Capacity);
    FreeStringPtr(ptr);
    string path = sb.ToString();
}
python
from ctypes import CDLL, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
ola.InputRecord(instance, 1, b"")
ola.InputRecord(instance, 0, b"")
ptr = ola.InputRecordGetPath(instance)
if ptr:
    buf = create_string_buffer(512)
    ola.GetStringFromPtr(ptr, buf, 512)
    ola.FreeStringPtr(ptr)
    path = buf.value.decode("utf-8")

返回值 ​

返回值说明
非 0成功，返回录制文件绝对路径的字符串指针。返回的字符串指针需要调用 FreeStringPtr 释放内存。
0失败。

注意事项 ​

项目说明
释放内存返回的字符串指针需要调用 FreeStringPtr 释放内存。
查询时机InputRecord(START) 之后即可查询；STOP 后路径仍有效，直到下次 START。
