11/// Denotes result values returned by system functions (glibc, etc).
12/// In case module \alib_camp is included in the \alibbuild, the enum record
13/// \alib{exceptions;ERException} is assigned and each error is resourced in the
14/// \alib{camp;Basecamp}.
15/// With that, these enums can be used as information entries in class \alib{exceptions;Exception}.
