Operations

These topics describe the VISA operations. The operation descriptions are listed in alphabetical order for easy reference.

Each event description contains a brief Purpose statement below the title. You will then see the operation defined in both ANSI C and Visual Basic version 4 syntax, with the parameters set in boldface type. A list indicating the supported resource classes, such as GPIB, Serial, etc. is followed by a table that describes each parameter and indicates whether it is an input or output parameter (or both, in some cases). The Return Values section describes the completion and error codes, followed by a detailed Description section. The Related Items section directs you toward related operations, attributes, events, or resource descriptions. If you want to know specifically about attributes, events, and operations of the INSTR Resource, for example, you should navigate to the INSTR Resource topic.
