votequorum_qdevice_master_wins – Sets or clears quorum device master_wins flag Synopsis #include <corosync/votequorum.h> int votequorum_qdevice_master_wins(votequorum_handle_t handle const char name, unsigned int allow); Description The votequorum_qdevice_master_wins informs votequorum whether or not the currently registered qdevice subsystem supports ‘master_wins’ mode (default 0). This mode allows the qdevice to effectively take over the quorum calculations of votequorum. Any node…

votequorum_initialize – Create a new connection to the VoteQuorum service Synopsis #include <corosync/votequorum.h> int votequorum_initialize(votequorum_handle_t *handle, votequorum_callbacks_t *callbacks); Description The votequorum_initialize function is used to initialize a connection to the vote-based quorum database API. Each application may have several connections to the votequorum API. Each application uses the handle argument to uniquely identify the connection….

votequorum_getinfo – Get information about the VoteQuorum service Synopsis #include <corosync/votequorum.h> int votequorum_getinfo(votequorum_handle_t *handle, unsigned int nodeid, struct votequorum_info *info); Description The votequorum_getinfo function is used to get information about the voting system and its nodes. The nodeid argument indicates which node information should be stored in the votequorum_info structure. The votequorum_info structure is defined…

votequorum_finalize – Terminate a connection to the votequorum service Synopsis #include <corosync/votequorum.h> int votequorum_finalize(votequorum_handle_t handle); Description The votequorum_finalize function is used to close a connection to the configuration dabatase API. Once the connection is finalized, the handle may not be used again by applications. No more callbacks will be dispatched from the votequorum_dispatch function. Return…

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 votequorum_dispatch(3) won’t block. The handle argument may not be used directly with poll because it is…

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…

votequorum_context_set – Sets the context variable for a VOTEQUORUM instance Synopsis #include <corosync/votequorum.h> int votequorum_context_set(votequorum_handle_t handle, void *context); Description The votequorum_context_set function is used to set the context variable for a votequorum instance. It has no meaning insire libvotequorum itself and will not be touched by the library. It can be retrieved using votequorum_context_get(3) Return…

votequorum_context_get – Gets the context variable for a VOTEQUORUM instance Synopsis #include <corosync/votequorum.h> int votequorum_context_get(votequorum_handle_t handle, void **context); Description The votequorum_context_get function is used to retrieve the context variable previously stored using votequorum_context_set(3) 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…
