Re: [go-nuts] Golang calling Windows DLL function with more than 18 arguments

2021-06-03 Thread George Vanev
The function is from a Chinese  SDK and I don't have the source code:
int HDAPI Hd_Rt_SendRealTimeText(int nSendType, void *pStrParams, int 
nRealTimeAreaIndex, int nMaxPageCount, int nColor, int nGray, int nX, int 
nY, int nWidth, int nHeight, 
void *pText, int nTextColor, int nBackGroupColor, int nStyle, void 
*pFontName, int nFontHeight, int nShowEffect, int nShowSpeed,int nStayTime, 
int nLiveTime, 
int bSaveToFlash, void *pDeviceGUID);

[go-nuts] Golang calling Windows DLL function with more than 18 arguments

2021-06-03 Thread George Vanev
I have an external 64 bit .DLL and I have to pass 22 arguments to one of 
the functions. Go (go1.16.4 windows/amd64) allows up to 18 arguments. Is 
there any workaround?
I've tried to make Syscall22 in dll_windows.go, link it with 
syscall_Syscall22 in src/runtime/syscall_windows.go and rebuilt: go install 
-a runtime. But it give me errors when trying to call the function
