Int SavePicToMemory (
Uint DeviceID,
Ref intptr cFrontImgBuf,
Ref intptr cRearImgBuf,
Ref int iFrontLen,
Ref int iRearLen)

CodePudding user response:

Call, should be

Intptr cFrontImgBuf=intprt. Zero;
Intptr cRearImgBuf=intprt. Zero;
Int iFrontLen=0;
Int iRearLen=0;

Int SavePicToMemory (1234, ref cFrontImgBuf, ref cRearImgBuf, ref iFrontLen, ref iRearLen)

Byte [] FrontImgData=https://bbs.csdn.net/topics/new byte [iFrontLen]
Marshal. Copy (cFrontImgBuf FrontImgData, 0, iFrontLen);

CodePudding user response:

Char * and ref intptr don't look right?

CodePudding user response:

Don't know whether you mean it, really can not empty what code restrictions

CodePudding user response:

Tried,, do not!!!!!!

CodePudding user response:

Char *, is actually a pointer, he can be any things

Generally when we translation is based on the context translation
He said, you give I preach a string, we write is a string
And he said, I return a string, we write is stringbuild

You here is that the meaning of context, he returned to the picture information data
We think he will give you byte [], and tell you the length of the byte array

Ref intptr is actually returns the byte array index 0 of the element pointer

Behind so we use the copy to copy from the memory from the pointer he start his designated the array length to our
