CC Mode 5.35.1 (C/*l); "Window scroll_bar" fontified as type |
Date: |
Sat, 05 Nov 2022 20:34:46 +0800 |
Package: cc-mode
Go to src/xterm.c in the Emacs source code. Then, type M-> and keep
pressing M-v until the beginning of the buffer is reached. Afterwards,
go to line 14458, around which will be the following function
definition:
MAYBE_UNUSED static void
xi_select_scroll_bar_events (struct x_display_info *dpyinfo,
Window scroll_bar)
{
XIEventMask mask;
unsigned char *m;
ptrdiff_t length;
length = XIMaskLen (XI_LASTEVENT);
mask.mask = m = alloca (length);
memset (m, 0, length);
mask.mask_len = length;
"scroll_bar" in "Window scroll_bar" will be fontified as a type!

I've convinced myself the patch is correct, so I've committed it and I'm
closing the bug. If the bug isn't quite fixed, we can reopen it.
