What are some ways to trace a pointer ?

Wow! You actually took the time to look through the codebase......
I was going to post the file locations within the repository, but I wasn't sure that anybody would bother to look.

You can set a data breakpoint to find when a variable is changed.

Yeah. I set breakpoints out the yinyang, and was still finding this problem difficult to understand.

I did some browsing though and PNL_CLOSED isn't a bit, it's actually two bits.From interface_intern.h

#define PNL_CLOSEDX    2
#define PNL_CLOSEDY    4
#define PNL_CLOSED    6

In interface_panel.c the X & Y bits are set individually at line 1045 & 1049 (just below the code you posted)

Oh Okay... I think I get how it works now. The X and Y bits are being used to denote when a panel is closed. I was expecting that an operation
like " block->panel->flag |= PNL_CLOSED " would probably be used.



THANK YOU dude, I'm on my way to becoming a professional. Good day.

EDIT:

Oh yeah. You seem to have definitely solved my immediate problem (breathing a sigh of relief ). Thank you so much... But I was still wondering about the 2 questions in my original post; I - think - it might be very helpful to me in the future. Would you or anybody else have an answer?
