Function Documentation

unsigned int LCM_initialize (  void   )

Initialize the LCM system. Return values: LCM_ALOCFAIL  Memory allocation failure LCM_BADSTAT  Not in state "uninitialized" (bad state transition) LCM_MUALOCFL  Cannot allocate a mutex LCM_SUCCESS  Success LCM_initialize() initializes the LAT Spacecraft Messages system.

unsigned int LCM_shutdown (  void   )

Shut down the LCM system. Return values: LCM_SUCCESS  Success LCM_shutdown() shuts down the LAT Spacecraft Messages system.

unsigned int LCM_start (  void   )

Start the LCM task. LCM_start() starts the LCM task. The LCM control state should be LCM_CTL_INITIALIZED before calling this function. On successful exit from this function, the LCM control state will be LCM_CTL_STARTING. As part of LCM's task start procedures, the LCM task first runs a one-time task initialization routine in LCM task context. If that is successful, the LCM control state is changed to LCM_CTL_RUNNING. Any failures along the way and the LCM control state is set to LCM_CTL_BROKEN.

unsigned int LCM_stop (  void   )

Stop the LCM task. The LCM control state should be LCM_CTL_RUNNING before calling this function (after calling LCM_start()). Sets LCM control state to LCM_CTL_INITIALIZED. This function is a replacement for LCM_stopTask(). Returns: A FILE MSG code.

static unsigned int LCM_taskInitialize (  LCM_Control *  ctl  )  [static]

Initialize the LCM task (elements common to all CPUs). Parameters: ctl  (in) LCM control block LCM_taskInitialize() builds up the CPU common elements of the LCM task.
