Struct

CoglPollFD

Description [src]

struct CoglPollFD {
  int fd;
  short int events;
  short int revents;
}

A struct for describing the state of a file descriptor that Cogl needs to block on. The events field contains a bitmask of CoglPollFDEvents that should cause the application to wake up. After the application is woken up from idle it should pass back an array of CoglPollFDs to Cogl and update the revents mask to the actual events that occurred on the file descriptor.

Note that CoglPollFD is deliberately exactly the same as struct pollfd on Unix so that it can simply be cast when calling poll.

Structure members
