From 204bbef0431933dce9eb0b8d4074d723a9f7345b Mon Sep 17 00:00:00 2001 From: Ulrich Sibiller Date: Tue, 13 Oct 2020 20:48:23 +0200 Subject: Clipboard.c: make use of the new helpers from Atoms.c This saves us from having to create intermediate strings and Xfreeing them again. Which can easily be forgotten, producing memleaks. --- nx-X11/programs/Xserver/hw/nxagent/Clipboard.c | 163 ++++++++----------------- 1 file changed, 50 insertions(+), 113 deletions(-) (limited to 'nx-X11') diff --git a/nx-X11/programs/Xserver/hw/nxagent/Clipboard.c b/nx-X11/programs/Xserver/hw/nxagent/Clipboard.c index 1aa2c050a..2d000a4f7 100644 --- a/nx-X11/programs/Xserver/hw/nxagent/Clipboard.c +++ b/nx-X11/programs/Xserver/hw/nxagent/Clipboard.c @@ -279,12 +279,12 @@ static void printSelectionStat(int index) { SelectionOwner lOwner = lastSelectionOwner[index]; Selection curSel = CurrentSelections[index]; - char *s = NULL; fprintf(stderr, "selection [%d]:\n", index); - SAFE_XFree(s); s = XGetAtomName(nxagentDisplay, remSelAtoms[index]); - fprintf(stderr, " selection Atom internal [%d][%s] remote [%ld][%s]\n", intSelAtoms[index], NameForAtom(intSelAtoms[index]), remSelAtoms[index], s); + fprintf(stderr, " selection Atom internal [%d][%s] remote [%ld][%s]\n", + intSelAtoms[index], NameForAtom(intSelAtoms[index]), + remSelAtoms[index], NameForRemAtom(remSelAtoms[index])); fprintf(stderr, " owner side %s\n", IS_INTERNAL_OWNER(index) ?
