WvFile
WvFile implements a stream connected to a file or Unix device.
Definition:
wvfile.h:28
WvFile::WvFile
WvFile()
Create an empty WvFile that you'll open later with open()
Definition:
wvfile.cc:10
IWvStream::SelectInfo
the data structure used by pre_select()/post_select() and internally by select().
Definition:
iwvstream.h:50
WvFile::pre_select
virtual void pre_select(SelectInfo &si)
pre_select() sets up for eventually calling ::select().
Definition:
wvfile.cc:129
WvFile::post_select
virtual bool post_select(SelectInfo &si)
post_select() is called after ::select(), and returns true if this object is now ready.
Definition:
wvfile.cc:138
WvFdStream
Base class for streams built on Unix file descriptors.
