Every GPIB library routine returns a 16-bit status word to the variable
(
ibsta
gpib-32.dll
describes the current condition of the GPIB bus lines and the GPIB
Interface Board. By examining the status word, the programmer may
determine what path the application program is to take.
Note that the mnemonics used to describe each bit of the status word are
defined within the header file for each language.
The status word contains 16-bits. If a bit equals 1 (set), the corresponding
condition is true. Likewise, if a bit equals 0, then the corresponding
condition has not occurred. The status word is of the format shown below.
If your application performs GPIB operations in multiple threads, your
application should examine the thread status function,
instead of the global
of
for a particular thread of execution. Along with
