◆ mpcomm_supervisor_init()

int mpcomm_supervisor_init ( mpcomm_supervisor_context_t **  ctx,
const char *  filepath,
uint8_t  helper_num 
)

Initialize the MPCOMM framework.

Parameters
[in]ctxContext with information about MPCOMM workers.
[in]filepathPath to controller and helper binary file.
[in]helper_numNumber of helpers to be used.
Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.

int mpcomm_supervisor_deinit ( mpcomm_supervisor_context_t ctx)

Deinitialize the MPCOMM framework.

Parameters
[in]ctxContext with information about MPCOMM workers.
Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.

◆ mpcomm_supervisor_send_controller()

int mpcomm_supervisor_send_controller ( mpcomm_supervisor_context_t ctx,
void *  data 
)

Send the user data to the controller for processing.

Parameters
[in]ctxContext with information about MPCOMM workers.
[in]dataUser data.
Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.

◆ mpcomm_supervisor_wait_controller_done()

int mpcomm_supervisor_wait_controller_done ( mpcomm_supervisor_context_t ctx,
const struct timespec *  abstime 
)

Wait until user data has been processed by controller.

Parameters
[in]ctxContext with information about MPCOMM workers.
[in]abstimeThe absolute time to wait until a timeout is declared.
Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.
