Author: kevans Date: Fri Mar 2 16:31:23 2018 New Revision: 330284 URL: https://svnweb.freebsd.org/changeset/base/330284 Log: liblua: Use putc instead of printf for printc printc does not need the features or the overhead of printf. It does not take formatting strings, and it pipes the single string argument through an "%s" format. Instead, use putc directly. This pipes the string through in its entirety as a series of 'unsigned char's, generally straight to the console emulator.
