Function
Retrieves limit status.
Format
Ret = SmcWGetLimitStatus( Id, AxisNo, LimitSts )
Parameters
Id [ C, C++: short ] [ Python: ctypes.c_short ]
Specify the device ID retrieved by SmcWInit function.
AxisNo [ C, C++: short ] [ Python: ctypes.c_short ]
Specify axis number.
LimitSts [ C, C++: short * ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specify the address of the variable that stores the limit status.

Example
The state of the limit of axis number 1 is acquired.
C, C++
long Ret;
short LimitSts ;
Ret = SmcWGetLimitStatus( Id , 1, &LimitSts );
Python
Ret = ctypes.c_long()
LimitSts = ctypes.c_short()
Ret.value = csmc.SmcWGetLimitStatus( Id , 1, ctypes.byref(LimitSts) )
