I want to call functions according to an exception. In C there is the

How do I check an exception type? For example:
std.socket.SocketOSException@std/socket.d(2857): Unable to connect
socket: Connection refused
??:? [0x459ec5]
??:? [0x4646e6]
??:? [0x44743d]
??:? [0x42c833]
??:? [0x404273]
??:? [0x404cf8]
??:? [0x440a43]
??:? [0x7fdeccecc3f8]
??:? clone [0x7fdeccc98b52]
or
Unable to connect socket: Connection refused
So do I just need to check the exception string? Or there is something
like errno in C?
In the case where you are actually looking to see what *type* the
exception is:
try {
... // socket code
}
catch(SocketException e)
{
// it's a socket exception here
}
catch(Exception e)
{
// otherwise, it's a different kind of exception
}
