opc function
This function sets the OPC bit in the status register when all overlapped commands are
completed.
Function
Sets the Operation Complete status bit when all overlapped commands are completed.
Usage
opc()
Remarks
• This function will cause the Operation Complete bit in the Standard Event Status Register
to be set when all previously started local overlapped commands are
complete. Note that each node will independently set their Operation Complete bits in
their own status models.
• Any nodes not actively performing overlapped commands will set their bits
immediately. All remaining nodes will set their own bits as they complete their own
overlapped commands.

Also see
printbuffer
and
printnumber
functions
These functions are used to print data and numbers.
makesetter
Function
Creates a function to set the value of an attribute.
Usage
setter = makesetter(table, attributename)
table
Read-only table where the attribute is located.
attributename
The string name of the attribute.
setter
Function that sets the value of the given attribute.
Remarks
• This function creates a function that when called sets the value of the attribute. This
function is useful for aliasing attributes to improve execution speed. Calling the
setter
function will execute faster than accessing the attribute directly.
• Creating a
setter
function is only useful if it is going to be called several times.
Otherwise the overhead of creating the
setter
function outweighs the overhead of
accessing the attribute directly.
Example
Creates a
setter
function called
setlevel
:
setlevel = makesetter(smua.source, "levelv")
for v = 1, 10 do
setlevel(v)
end
Using
setlevel
in the loop sets the value of
smua.source.levelv
, thereby
performing a source sweep.
opc
printbuffer
Function
Prints data from tables and reading buffer sub-tables.
