= get =
== Syntax ==
:{{int get(int item)}}
== Arguments ==
:'''item'''
::Numeric identifier of an item in the buffer.
== Return ==
:The value of the buffered item requested.
== Description ==
:FilterMeister has a small internal buffer of {{N_CELLS}} integer items which can be accessed by means of the {{get}} and {{put}} functions. They provide the simplest means for storaging integer data since they require no variable to be declared.
:Currently {{N_CELLS}} is 1024.  It may increase in future releases of FilterMeister, but will never decrease. {{N_CELLS}} will always be a power of 2.
:By default, the items in the buffer are initialized to zero at the end of the executing code block. Calling the {{cell_preserve(1)}} function changes this behavior so the buffer values are stored between separate handlers, making them ideal for transporting information between them.
:The {{get}} function takes an integer argument in the range of 0 up to and including {{(N_CELLS - 1)}} and returns the value stored in that position in the buffer.
== Example ==
<code>
%ffp

OnFilterStart:
{
    put(10, 0);
    Info("The value of buffer position 0 is %d", get(0));
}
</code>
