# STEP 0;
# I recommend downloading or building the latest
# version of llvm with clang and the clang-tidy
# tools in a private repo. NOTE: Apple does
# not currently distribute these.
#
# STEP 1:
# Build your source tree with cmake and use
# export PATH=${MYCLANG_FROM_STEP0}:$PATH
# export CXX=${MYCLANG_FROM_STEP0}
# export CC=${MYCLANG_FROM_STEP0}
# cd ${MYBLD}
# cmake -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=ON ${MYSRC}
# to generate the compile_commands.json
# comple options database files.
#
# STEP 2:
# Run clang-tidy with the

STYLE: Remove unused parameters
Finds unused function parameters. Unused parameters may signify a bug in the
code (e.g. when a different parameter is used instead). The suggested fixes
either comment parameter name out or remove the parameter completely, if all
callers of the function are in the same translation unit and can be updated.
