# Usage: cppcheck-wrapper.sh <file>
# Notes on suppressions
# - readdir_r is deprecated. See readdir_r(3)
# - We allow strtok if threadsafety is not a consideration
# - With the C89 kernel style, variableScope throws warnings, but not a problem
# - vsnprintf() is used in accordance with the man page, so not sure what the
# issue is
# - list.h and hashmap.{c,h} are copied from git/linux, so it's easier to keep
# them complete. It also makes the unit test work properly
