Locale-Sensitive Perl Method

readlink EXPR;


Internationalization (I18n) Method Overview

The readlink function returns the value of a symbolic link.

See perl's readlink function documentation and perlunicode for additional details.

I18n Issues

Perl does attempt to resolve Unicode text input to the readlink function. The input is instead provided as bytestrings. The proper encoding for strings passed to this function may be dependent on the operating and file system(s). For example, Unicode may or may not be allowed in file names. And the exact Unicode encoding may differ on different platforms ('UTF-8', 'UTF-16 Big Endian', etc.).

Whether readlink constitutes an i18n issue will depend on its usage in the application, and what architecture it can be expected to run on.

Suggested Replacement

Use care when providing byte-strings to system. Double check that the provided argument(s) will be tuned for the correct system architecture and encoding.

Globalyzer will detect this function and report it as an i18n issue. If you have determined that the call is being handled correctly, you can use Globalyzer's Ignore Comment functionality to ensure that it isn't picked up in a subsequent scan.
