[Discuss-gnuradio] GRC GUI parameters for custom blocks

[Vipin Sharma]

Hi,

I have a custom block, say CustomBlock, which takes two arguments, arg0 and 
arg1. My intention is to have these arguments be configured through gui after 
the custom block is instantiated. I define <param> entries for these arguments 
in the xml file for the CustomBlock which allows GRC gui to let me configure 
the arguments interactively.

I am trying to understand the relation ship between GRC GUI custom block 
parameters and the CustomBlock C code’s function arguments. How does GRC 
framework pass GUI parameters to its associated C function which also has the 
same arguments?
