+ * from that string.
+ *
+ * Upon return, the input character pointer pointed to by the parameter s
+ * is updated to point to the remainding, unscanned, portion of the string,
+ * or to a null character if the entire string has been consummed.
+ *
+ * This function returns a pointer to a null-terminated string which

+ * token could be isolated.
+ *
+ * Note the side effect of modifying the input string s by the insertion
+ * of a null character, making it two strings.
+ *
+ * See "Parsing C Command-Line Arguments" in the MSDN Library for the
+ * parsing rule details. The rule summary from that specification is:
+ *
+ * * Arguments are delimited by white space, which is either a space or a tab.
+ *
+ * * A string surrounded by double quotation marks is interpreted as a single
+ * argument, regardless of white space contained within. A quoted string can
+ * be embedded in an argument. Note that the caret (^) is not recognized as
+ * an escape character or delimiter.
+ *
+ * * A double quotation mark preceded by a backslash, \", is interpreted as a
+ * literal double quotation mark (").
+ *
+ * * Backslashes are interpreted literally, unless they immediately precede a
+ * double quotation mark.
+ *
+ * * If an even number of backslashes is followed by a double quotation mark,
+ * then one backslash (\) is placed in the argv array for every pair of
+ * backslashes (\\), and the double quotation mark (") is interpreted as a
+ * string delimiter.
+ *
+ * * If an odd number of backslashes is followed by a double quotation mark,
+ * then one backslash (\) is placed in the argv array for every pair of
+ * backslashes (\\) and the double quotation mark is interpreted as an
+ * escape sequence by the remaining backslash, causing a literal double
