On ncurses-6.3 with extra printf() annotations gcc now detects
use of user input in place of format strings:
gptcurses.cc:274:10: error:
format not a string literal and no format arguments [-Werror=format-security]
274 | printw(theLine.c_str());

Subject: [PATCH:gptfdisk] gptcurses.cc: always use "%s"-style format for printf()-style
|
|
functions
|
|
|
|
`ncuses-6.3` added printf-style function attributes and now makes
|
|
it easier to catch cases when user input is used in palce of format
|
|
string when built with CFLAGS=-Werror=format-security:
|
|
|
|
gptcurses.cc:274:10: error:
|
|
format not a string literal and no format arguments [-Werror=format-security]
|
|
274 | printw(theLine.c_str());
|
|
| ~~~~~~^~~~~~~~~~~~~~~~~
|
|
|
|
Let's wrap all the missing places with "%s" format.
