+/**
+ * NAME
+ * escape_string
+ *
+ * DESCRIPTION
+ * escape_string quotes and escapes a string to be usable with collectd's
+ * plain text protocol. "simple" strings are left as they are, for example if
+ * buffer is 'simple' before the call, it will remain 'simple'. However, if
+ * buffer contains 'more "complex"' before the call, the returned buffer will
+ * contain '"more \"complex\""'.
+ *
+ * If the buffer is too small to contain the escaped string, the string will
+ * be truncated. However, leading and trailing double quotes, as well as an
+ * ending null byte are guaranteed.
+ *
+ * RETURN VALUE
+ * Returns zero on success, even if the string was truncated. Non-zero on
+ * failure.
