       visa - Virtual Instrument Software Architecture

SYNOPSIS

       #include <visa.h>

DESCRIPTION

       The Virtual Instrument Software Architecture provides a generic interface for communication with test and
       measurement equipment.

   Resource Names
       Each  device  is  identified  by  a  resource  name  that specifies the type of connection used, location
       information and the device type.

       USB Devices
              USB[bus]::manufacturer::product::serial[::type]

              The manufacturer and product identifiers must be given as hexadecimal numbers  prefixed  with  0x.
              The serial number is mandatory, even if the device would be unique otherwise.

       Ethernet/VXI-11 Devices
              TCPIP[interface]::host[::type]

   Resource Manager
       Access  to  resources  is  mediated through a resource manager; while technically there could be multiple
       instances, usually only the default resource manager is used.

       A handle to the default resource manager can be obtained from the viOpenDefaultRM(3visa) function.

   Finding Devices
       If the resource name is not known in advance, the resource manager can be queried for  a  list  of  known
       devices by using the viFindRsrc(3visa) function.

       This  function  returns  a  ViFindList object (along with the first known resource), and further resource
       names are then queried from the find list using viFindNext(3visa) before finally freeing the  list  using
       viClose(3visa).
