Overview
All ACI function calls and ACI structures are defined in the
aci.h header file. ACI functions return 0 or -1 for successful
and unsuccessful command execution respectively. A
command failure sets the DAS error code variable d_errno to
the specific error code. In such case, a text error message may
be written to standard error by calling aci_perror, which
accepts a user defined message string and attaches it to the
DAS error message.
aci_barcode
The aci_barcode function switches the barcode reader for the
volser on the robot on or off. See Figure 4-1.
