What does "Gai" GaiException and EAI for / mean?

There is no javadoc. Can anyone please explain what exactly the "Guy" GaiException means? Like EAI?

Lines 22-27 of the file GaiException.java

indicate the following:

/ ** Unchecked exception thrown when {@link Os} {@code getaddrinfo} or {@code getnameinfo} * methods do not work. This exception contains a native error value, for comparison to * {@code GAI_} constants in {@link OsConstants} must be complex * callers need to tweak their behavior based on the exact error. * /

Based on the wording @code getaddrinfo

, it looks like it means Get Address Information .

OS interface

The method is getaddrinfo

defined in the interface file Os.java

on line 50:



public InetAddress[] getaddrinfo(String node, StructAddrinfo hints) throws GaiException;

OS interface implementations

The method getaddrinfo

is then implemented (via the Os interface) ForwardingOs.java

on line 59:

public InetAddress[] getaddrinfo(String node, StructAddrinfo hints) throws GaiException {
    return os.getaddrinfo(node, hints);
}

The functionality is ForwardingOs.java

then inherited from BlockGuardOs.java (and not overridden)
