<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div><span style="font-weight: bold;">Hi guys,</span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new york,times,serif; background-color: transparent; font-style: normal;"><span style="font-weight: bold;">I try to writte a small clock application in C. I have 3 files yet, </span><span>functions.h</span><span style="font-weight: bold;">, </span><span>functions.c</span><span style="font-weight: bold;">, </span><span>main.c</span><span style="font-weight: bold;">. I'm using a structure wich contains a </span><span>cairo_t</span><span style="font-weight: bold;"> and a </span><span>cairo_surface_t</span><span style="font-weight: bold;"> that I need to update during the running of the application. For having this I'm using a structure defined in </span><span>function.h</span><span style="font-weight: bold;">, I'm a little suspicious about how I use this st</span><span style="font-weight: bold;">ructure, I do some cast ( </span><span>(*_mc)</span><span style="font-weight: bold;"> ) but I'm not sure that's well written, (I never written something so funky...), could you just take a look and told me if it's correct. gcc doesn't complains, and I don't get any runtime error, so I'm just looking for a critic or an advice.</span></div><div style="color: rgb(0, 0, 0);
