From 04593e8ec4bac2606dec54605c72a6a49cc83f9b Mon Sep 17 00:00:00 2001 From: Berthold Stoeger Date: Sun, 24 Mar 2019 21:50:01 +0100 Subject: Cleanup: fix printGPSCoords signature and leaks The printGPSCoords() function returns a copied C-style string. Since the owndership is transferred to the caller, the correct return type is "char *" instead of "const char *". Thus a number of casts when calling free can be removed. Moreover a number of callers didn't free the string and thus were leaking memory. Fix them. Ultimately we might want two versions of the function: one for QString, one for C-style strings.
