NAME¶

miniasync_vdm_synchronous - synchronous implementation of miniasync(7) virtual data mover

SYNOPSIS¶

#include <libminiasync.h>
    

For general description of virtual data mover API, see miniasync(7).

DESCRIPTION¶

Synchronous data mover is a synchronous implementation of the virtual data mover interface.

When the future is polled for the first time the data mover operation will be executed synchronously on the same thread that polled the future.

To create a new synchronous data mover instance, use data_mover_sync_new(3) function.

Synchronous data mover supports following operations:

•

vdm_memcpy(3) - memory copy operation

•

vdm_memmove(3) - memory move operation

•

vdm_memset(3) - memory set operation

Synchronous data mover does not support notifier feature. For more information about notifiers, see miniasync_future(7).

For more information about the usage of thread data mover API, see examples directory in miniasync repository <https://github.com/pmem/miniasync>.

EXAMPLE¶

Example usage of synchronous data mover vdm_memcpy(3) operation:

struct data_mover_sync *dms = data_mover_sync_new();
struct vdm *sync_mover = data_mover_sync_get_vdm(dms);
struct vdm_memcpy_future memcpy_fut =


        vdm_memcpy(sync_mover, dest, src, copy_size, 0);
