Get Error Contents

By using function ZmGetErrorString, it is possible to convert error code to a character string for all functions.
The character string used by function ZmGetErrorString is 256 bytes at most.

Programming Example in C

long Ret;
long ErrorRet;
short Id;
char ErrorString[256];

Ret = ZmInit( "ZM000" , &Id );
ErrorRet = ZmGetErrorString( Ret , ErrorString );
printf("ZmInit : %s", ErrorString );

Ret = ZmExit( Id );
ErrorRet = ZmGetErrorString( Ret , ErrorString );
printf("ZmExit：%s", ErrorString );

Programming Example in Python

Ret = ctypes.c_long()

ErrorRet = ctypes.c_long()

Id = ctypes.c_short()

ErrorString = ctypes.create_string_buffer(256)

Ret.value = czm.ZmInit ( b"ZM000" , ctypes.byref(Id) )

ErrorRet.value = czm.ZmGetErrorString( Ret, ErrorString )

print( f"ZmInit : {ErrorString.value.decode('utf-8')}" )

Ret.value = czm.ZmExit ( Id )

ErrorRet.value = czm.ZmGetErrorString( Ret, ErrorString )

print( f"ZmExit : {ErrorString.value.decode('utf-8')}" )
