* This is a grab bag of functions for string operations, designed to enhance
* the standard string.h; these are separated from the non-tal-needing
- * string utilities in "str.h".
+ * string utilities in "str.h". Each string created by this library
+ * will have tal_count() equal to strlen() + 1 (assuming you didn't create
+ * a string containing a NUL, such as using tal_fmt("%c", 0)).
*
* Example:
* #include <ccan/tal/str/str.h>
* char *textfile;
* char **lines;
*
+ * if (argc > 2)
+ * errx(1, "Takes 0 or 1 arguments");
* // Grab lines in file.
* textfile = grab_file(NULL, argv[1]);
* if (!textfile)
