pledge(2) cscope

Browse Source 
If linemode == NO it needs:

rpath: read the program
wpath: create cscope.out files
cpath: needs to unlink temp files at exit
tty: at exit curses calls an ioctl to clean the window
proc/exec: needs to fork and exec external program, namely $EDITOR

If linemode == YES it's the same as above, except it doesn't need "tty"
