C++ (Cpp) lo_bundle_length Examples

Example #1

File: bundle.c Project: foogywoo/drone

{
    size_t s, skip;
    int32_t *bes;

Example #2

File: send.c Project: Zillode/OSCeleton-OpenNI

int lo_send_bundle_from(lo_address a, lo_server from, lo_bundle b)
{
    const size_t data_len = lo_bundle_length(b);
    char *data = lo_bundle_serialise(b, NULL, NULL);

    // Send the bundle
    int ret = send_data( a, from, data, data_len );

    // Free the memory allocated by lo_bundle_serialise
    if (data) free( data );
