* Atoms.c: add explanation for PVS Studio warningUlrich Sibiller2021-01-151-0/+3
| | | | | "V575 The potential null pointer is passed into 'strlen' function. Inspect the first argument. Check lines: 420, 403."
* NXpicture.c: remove unneccessary checkUlrich Sibiller2021-01-151-15/+12
| | | | | | | Code can only be reached if pPicture is non-NULL. Besides, pPicture will be accessed later anyway, regardless of this check. Finding of PVS Studio: "V547 Expression 'pPicture != NULL' is always true."
* Keyboard.c: simplify codeUlrich Sibiller2021-01-151-5/+3
| | | | Based on PVS Studio finding: "V547 Expression 'data' is always true."
* Colormap.c: remove unneccessary checkUlrich Sibiller2021-01-151-1/+1
| | | | | | | | success would always be true at the beginning of the loop as it is part of the loop condition. Finding from PVS Studio: "V560 A part of conditional expression is always true: success."
* Colormap.c: fix parenthesesUlrich Sibiller2021-01-151-1/+1
| | | | | | PVS Studio: "V592 The expression was enclosed by parentheses twice: '((* pRed * (limg + 1)))'. One pair of parentheses is unnecessary or misprint is present."
* Atoms.c: silence PVS Studio warningUlrich Sibiller2021-01-151-2/+6
| | | | | | "V701 realloc() possible leak: when realloc() fails in allocating memory, original pointer 'privAtomMap' is lost. Consider assigning realloc() to a temporary pointer."
* Atoms.c: cosmetics in nxagentWriteAtom()Ulrich Sibiller2021-01-151-1/+2
|
* Atoms.c: fix strlen(NULL)Ulrich Sibiller2021-01-151-1/+1
| | | | | FIX PVS Studio finding "V575 The potential null pointer is passed into 'strlen' function. Inspect the first argument"
* nxagent: make full screen mode selectable at startupUlrich Sibiller2021-01-154-9/+33
| | | | | | | | fullscreen= now accepts the new value "2" for a fullscreen covering only one screen. -geometry and geometry= now know additional keywords "allscreens" and "onescreen". Fixes ArcticaProject/nx-libs#923
