I have clang-tidy checking for unused return values with bugprone-unused-return-value check. Unfortunately it only checks return values from list of functions specified with CheckedFunctions parameter. I would like to check usage of return value from all functions, but am not able to figure out what to write to CheckedFunctions to do this.

What should I write to bugprone-unused-return-value's parameter CheckedFunctions for it to check all functions?

Unfortunately bugprone-unused-return-value check is not built to check all functions.

You can either specify CheckedFunctions or if you omit the specification then a default list of functions will be used. There is no possibility of using wildcards or regular expressions here.

See the documentation. I also checked the source code of the check just to be sure but in current version of clang-tidy (14) this can't be done.
