From 5cd4e8c3999aca48ed51b82e7c5c21392d80ab2f Mon Sep 17 00:00:00 2001 From: Patrick Roncagliolo Date: Sat, 7 Jan 2017 00:16:34 +0100 Subject: Change double quotes to single quotes - "." is a string literal, and so is treated as the char '.' plus the null char '\0'. - Single quotes reduces the necessary memory for this literal to only one char instead. A string literal as the one actually present may require the use of the method "write(const char *str)", so there could be also a performance overhead. - Another reason to change quotes style is for consistency with line 235.
