The OIA Group consists of the bits that show the status of the
connected sessions. The group is categorized by the represented host
function. (For example, Group 8 consists of the bits that show all
conditions of the input inhibit in the session.) The states of each
group are ordered so that the high-order bits represent the indicators
of higher priority. That is, bit 7 has priority over bit 0. Therefore,
if more than one state is active within a group, the state with the
highest priority is the active state within that group.
To use this function, preallocate memory to receive the returned
data string parameter. The statements required to preallocate this
memory vary depending on the language in which your application is
written. Refer to Memory Allocation for more information.
