VOTEQUORUM_FD_GET(3)				    Corosync Cluster Engine Programmer's Manual 			      VOTEQUORUM_FD_GET(3)

NAME
votequorum_fd_get - Dispatches callbacks from the votequorum service SYNOPSIS
#include <corosync/votequorum.h> int votequorum_fd_get(votequorum_handle_t handle, int *fd); DESCRIPTION
The votequorum_fd_get function is used to retrieve the file descriptor that may be used with the poll system call to determine when vote- quorum_dispatch(3) won't block. The handle argument may not be used directly with poll because it is not the file descriptor, but instead an internal identifier used by the votequorum library. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
CS_ERR_TRY_AGAIN Resource temporarily unavailable CS_ERR_INVALID_PARAM Invalid argument CS_ERR_ACCESS Permission denied CS_ERR_LIBRARY The connection failed CS_ERR_INTERRUPT System call inturrupted by a signal CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported CS_ERR_MESSAGE_ERROR Incorrect auth message received CS_ERR_NO_MEMORY Not enough memory to completed the requested task SEE ALSO

NAME
votequorum_dispatch - Dispatches callbacks from the votequorum service SYNOPSIS
#include <corosync/votequorum.h> int votequorum_dispatch(votequorum_handle_t handle, cs_dispatch_flags_t *dispatch_types); DESCRIPTION
The votequorum_dispatch function is used to dispatch configuration changes. Each application may have several connections to the votequorum API. Each application uses the handle argument to uniquely identify the connection. The dispatch_types argument is used to identify the type of dispatch to execute. The possible types are defined by the structure: typedef enum { CS_DISPATCH_ONE = 1, CS_DISPATCH_ALL = 2, CS_DISPATCH_BLOCKING = 3, CS_DISPATCH_ONE_NONBLOCKING = 4 } cs_dispatch_flags_t; The dispatch values have the following meanings: CS_DISPATCH_ONE Dispatch at least one callback, blocking until the callback is dispatched. CS_DISPATCH_ALL Dispatch all waiting callbacks without blocking to wait for any callbacks. CS_DISPATCH_BLOCKING Dispatch all callbacks blocking indefinitely. This is used in a threaded program where a thread is created, and then quorum_dis- patch() is called immediately from the created thread to execute callbacks. CS_DISPATCH_ONE_NONBLOCKING Dispatch at most one callback. If there is no pending callback, CS_ERR_TRY_AGAIN is returned. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
CS_ERR_TRY_AGAIN Resource temporarily unavailable CS_ERR_INVALID_PARAM Invalid argument CS_ERR_ACCESS Permission denied CS_ERR_LIBRARY The connection failed CS_ERR_INTERRUPT System call inturrupted by a signal CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported CS_ERR_MESSAGE_ERROR Incorrect auth message received CS_ERR_NO_MEMORY Not enough memory to completed the requested task SEE ALSO
