NAME

SYNOPSIS

int quorum_dispatch(quorum_handle_t handle, cs_dispatch_flags_t *dispatch_types);

DESCRIPTION

Each application may have several connections to the quorum 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_dispatch() 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

ERRORS

CS_ERR_INVALID_PARAM Invalid argument

CS_ERR_ACCESS Permission denied

CS_ERR_LIBRARY The connection failed

CS_ERR_INTERRUPT System call interrupted by a signal

CS_ERR_NOT_SUPPORTED The requested protocol/functionality not supported

CS_ERR_MESSAGE_ERROR Incorrect auth message received

CS_ERR_NO_MEMORY Not enough memory to complete the requested task
