Member Function Documentation

int CUdpSocket::fdType ( ) const

inlinevirtual

Get type id of this object.

Any concrete class derived from IFileDesc shall define a distinct type id named kFdType, so it's possible to check this id and determine what the object really is.
Currently following kFdTypes are defined:

Type Id	Value
CFile::kFdType	1
CTcpConnSocket::kFdType	2
CListenSocket::kFdType	3
CUdpSocket::kFdType	4
CPosixShmFile::kFdType	5
CEpoll::kFdType	6

Returns

Type id of this object

See also

kFdType

Implements IFileDesc.

const char* CUdpSocket::fdTypeName ( ) const

inlinevirtual

Get type name of this object.

Any concrete class derived from IFileDesc must give a readable name to identify itself.

Returns

Readable type name

Implements IFileDesc.
