You must then use peek4u() to read each value from its location in memory.

i.e.

atom pRegOptions, -- pointer
    vRegOptions -- value

-- allocate vars
pRegOptions = allocate( 4 ) -- INT

-- call function

-- read values
vRegOptions = peek4u( pRegOptions )

-- free memory
free( pRegOptions )

-- use values
