interlocked_exchange_add

interlocked_exchange_add( *Variable, Expression );

[*Variable (Addend)]

A reference to a variable (most of the time a global variable) to add the value of the resulting instruction to it.

[Expression (Value)]

The value which is added to the global variable.

Performs an atomic addition of two values.

The function returns the initial value of the Variable(Addend) parameter.

Result = interlocked_exchange_add(.my_gloabl_counter, 0x55);

Adds the value (0x55) to the global variable and saves the initial value of the .my_gloabl_counter into a local variable named Result.

You can also perform the subtraction by addition (using the 2's-complement system).
