Hi, I need to define a function x_y() as its mandatory to implement in my layer. But we want definition of z() for that So i do something like this in x.c:
void x_y()
{
}
#undef x_y
#define x_y z
It works.
What i don't understand is even though i define in c file, it works?
What happens at pre-processing level and what at linking level ?
Thanks,
Raj
