Format
(VB.NET)
Dim UpperCode, Ret As Integer
Ret = GpUpperCode(UpperCode)
(C)
DWORD UpperCode, Ret;
Ret = GpUpperCode(UpperCode);
(C#)
uint UpperCode, Ret;
Ret = gpib.UpperCode(UpperCode);
(Python)
UpperCode, Ret = ctypes.c_ulong(), ctypes.c_ulong()
Ret.value = GpibPy.GpUpperCode(UpperCode)
Mode Master mode / Slave mode
Parameters
UpperCode : valid / invalid of Upper bytes of a return value of function.
0 : Invalid
1 : Valid
Ret : End information(Return value)
0 : Normal completion
