int smr_write(struct smr *robot);

Smr_write communcates with the smr daemon [smrd], sending fields in the [[struct smr]] pointed to by ''robot'' for
transmission in a subsequent sample period.

Smr_write uses some of the fields in *robot as input parameters.

Ordinarily, zero is returned. If case of error, for example if communication is not possible, a non-zero value is returned.

'''Input parameters'''

The following fields are read by smr_write:
robot->write_flags: An ORed combination of flags, indicating which data smr_write should send.
robot->left.speed, robot->right.speed: Motor speed reference values.
robot->msg: Asynchronous message to send.

The valid write flags are:
SMR_FLAG_LV: Left motor speed.
SMR_FLAG_RV: Right motor speed.
SMR_FLAG_AM: Asynchronous message.
