- * \section pj_pstr_not_null_sec PJLIB String is NOT Null Terminated!
- *
- * That is the first information that developers need to know. Instead
- * of using normal C string, strings in PJLIB are represented as
- * pj_str_t structure below:
- *
- * <pre>
- * typedef struct pj_str_t
- * {
- * char *ptr;
- * pj_size_t slen;
- * } pj_str_t;
- * </pre>
- *
- * There are some advantages of using this approach:
- * - the string can point to arbitrary location in memory even
- * if the string in that location is not null terminated. This is
- * most usefull for text parsing, where the parsed text can just
- * point to the original text in the input. If we use C string,
- * then we will have to copy the text portion from the input
- * to a string variable.
- * - because the length of the string is known, string copy operation
- * can be made more efficient.
- *
- * Most of APIs in PJLIB that expect or return string will represent
- * the string as pj_str_t instead of normal C string.
- *
- * \section pj_pstr_examples_sec Examples
- *
- * For some examples, please see:
