getting code length and begin pointer

[McGreg]

I got some functions defined like this:

#pragma code_seg(push, r1, ".mycode")

void function1(....)
{
...
}

void function2 .....


#pragma code_seg(push, r1, ".mycode")

i want to know where in the memory .mycode begins, and where it ends/how long it is. how can i get that information from?

some kind of pointer and sizeof to the r1 identifier?
