getinstattr

This command returns configured instrument attributes.

int getinstattr(int instr_id, char *attrstr, char *attrvalstr);

All instruments in the system configuration have specific attributes. GPIB address is an example of an

attribute. The values of these attributes change as the system configuration is changed. Therefore, by

getting the values of key attributes at run time, user modules can be developed in a configuration-

independent manner. Given an instrument identification code and an attribute name string, this

module returns the specified attribute value string.

If the attribute value string exists, the returned string will match one of the values shown in the

Attribute value string column of the following table. If the requested attribute does not exist, the

attrvalstr parameter is set to a null string.

Possible values for the getinstattr parameters are listed in the following table.
