Disables the processing of flags that load values from secondary sources, specifically --flagfile, --fromenv, and --tryfromenv. When disabled, occurrences of these flags on the command line are skipped without opening files or inspecting environment variables, and a warning is printed to stderr. Direct command-line flags passed via argv are still parsed normally.

void
DisableFlagfileAndEnvParsing();This is primarily intended as a security precaution for privileged or setuid processes parsing untrusted command lines prior to dropping privileges.
Should only be called in main() before calling absl::ParseCommandLine() or absl::ParseAbseilFlagsOnly().
