|---|---|
group |
The group whose shared variable is to be accessed |
fid |
The field ID of the shared variable |
isNull |

Examples
This code gets the value of a shared variable of type integer:
curGroup = session -> GetCurrGroup();
fid = session -> GetSharedVarID(curGroup, "i_svar");
if (fid == 0xffff)
{
MessageBox(NULL, "Illegal fid!", "default", MB_OK);
return;
}
i_val = session-> GetIntSharedVar(curGroup, fid,
isNull);
session-> SetIntSharedVar(curGroup, fid, i_val+1);
