From 9803fc41e8e6a820634f41d2196bdced7cbbc99f Mon Sep 17 00:00:00 2001 From: Daniel Friesel Date: Wed, 17 Oct 2018 20:40:17 +0200 Subject: Use random() instead of rand() to increase portability Quoting glibc rand(3): The versions of rand() and srand() in the Linux C Library use the same random number generator as random(3) and srandom(3), so the lower-order bits should be as random as the higher-order bits. However, on older rand() implementations, and on current implementations on different systems, the lower-order bits are much less random than the higher-order bits. Do not use this function in applications intended to be portable when good randomness is needed. (Use random(3) instead.) --- src/wallpaper.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/wallpaper.c') diff --git a/src/wallpaper.c b/src/wallpaper.c index db14a8c..ef7ecca 100644 --- a/src/wallpaper.c +++ b/src/wallpaper.c @@ -252,7 +252,7 @@ void feh_wm_set_bg(char *fil, Imlib_Image im, int centered, int scaled, XGCValues gcval; GC gc; char bgname[20]; - int num = (int) rand(); + int num = (int) random(); char bgfil[4096]; char sendbuf[4096]; -- cgit v1.2.3
