# cppcheck.sh -- static analysis for the DVX source tree.
|
|
#
|
|
# Usage:
|
|
# ./cppcheck.sh # whole tree
|
|
# ./cppcheck.sh src/widgets # one subtree
|
|
# ./cppcheck.sh src/libs/kpunch/texthelp/textHelp.c # one file
|
|
#
|
|
# Exits 0 even when warnings are found -- cppcheck's exit status is
|
|
# not useful as a gate for this codebase (too many DJGPP-isms it can't
|
|
# resolve). Read the output.
