A 'GI.Gst.Structs.Poll.Poll' keeps track of file descriptors much like fd_set (used with
@/select()/@) or a struct pollfd array (used with @/poll()/@). Once created with
@/gst_poll_new()/@, the set can be used to wait for file descriptors to be
readable and\/or writable. It is possible to make this wait be controlled
by specifying 'True' for the /@controllable@/ flag when creating the set (or
later calling 'GI.Gst.Structs.Poll.pollSetControllable').

New file descriptors are added to the set using 'GI.Gst.Structs.Poll.pollAddFd', and
removed using 'GI.Gst.Structs.Poll.pollRemoveFd'. Controlling which file descriptors
should be waited for to become readable and\/or writable are done using
'GI.Gst.Structs.Poll.pollFdCtlRead', 'GI.Gst.Structs.Poll.pollFdCtlWrite' and 'GI.Gst.Structs.Poll.pollFdCtlPri'.

Use 'GI.Gst.Structs.Poll.pollWait' to wait for the file descriptors to actually become
readable and\/or writable, or to timeout if no file descriptor is available
in time. The wait can be controlled by calling 'GI.Gst.Structs.Poll.pollRestart' and
'GI.Gst.Structs.Poll.pollSetFlushing'.

Once the file descriptor set has been waited for, one can use
'GI.Gst.Structs.Poll.pollFdHasClosed' to see if the file descriptor has been closed,
'GI.Gst.Structs.Poll.pollFdHasError' to see if it has generated an error,
'GI.Gst.Structs.Poll.pollFdCanRead' to see if it is possible to read from the file
descriptor, and 'GI.Gst.Structs.Poll.pollFdCanWrite' to see if it is possible to
write to it.
