core.sys.linux.epoll

D header file to interface with the Linux epoll API (http://man7.org/linux/man-pages/man7/epoll.7.html). Available since Linux 2.6
EPOLL_CTL_ADD
Add a file descriptor to the interface.
EPOLL_CTL_DEL
Remove a file descriptor from the interface.
EPOLL_CTL_MOD
Change file descriptor epoll_event structure.
nothrow @nogc int epoll_create(int size);
Creates an epoll instance.
Parameters:
int size a hint specifying the number of file descriptors to be associated with the new instance. T
Returns:
an fd for the new instance. The fd returned by epoll_create() should be closed with close().
See Also:
epoll_create1 (int flags)
nothrow @nogc int epoll_create1(int flags);
Creates an epoll instance.
Parameters:
int flags a specified flag. If flags is 0, then, other than the fact that the obsolete size argument is dropped, epoll_create1() is the same as epoll_create().
Returns:
an fd for the new instance. The fd returned by epoll_create() should be closed with close().
See Also:
epoll_create (int size)
nothrow @nogc int epoll_ctl(int epfd, int op, int fd, epoll_event* event);
Manipulate an epoll instance
Parameters:
int epfd an epoll file descriptor instance
int op one of the EPOLL_CTL_* constants
int fd target file descriptor of the operation
epoll_event* event describes which events the caller is interested in and any associated user dat
Returns:
0 in case of success, -1 in case of error ( the "errno" variable will contain the specific error code )
nothrow @nogc int epoll_wait(int epfd, epoll_event* events, int maxevents, int timeout);
Wait for events on an epoll instance.
Parameters:
int epfd an epoll file descriptor instance
epoll_event* events a buffer that will contain triggered events
int maxevents the maximum number of events to be returned ( usually size of "events" )
int timeout specifies the maximum wait time in milliseconds (-1 == infinite)
Returns:
the number of triggered events returned in "events" buffer. Or -1 in case of error with the "errno" variable set to the specific error code.
nothrow @nogc int epoll_pwait(int epfd, epoll_event* events, int maxevents, int timeout, const sigset_t* ss);
Wait for events on an epoll instance
Parameters:
int epfd an epoll file descriptor instance
epoll_event* events a buffer that will contain triggered events
int maxevents the maximum number of events to be returned ( usually size of "events" )
int timeout specifies the maximum wait time in milliseconds (-1 == infinite)
sigset_t* ss a signal set. May be specified as null, in which case epoll_pwait() is equivalent to epoll_wait().
Returns:
the number of triggered events returned in "events" buffer. Or -1 in case of error with the "errno" variable set to the specific error code.
