- * @function kdebug_trace_string
- *
- * @discussion
- * This function emits strings to kdebug trace along with an ID and allows
- * for previously-traced strings to be overwritten and invalidated.
- *
- * To start tracing a string and generate an ID to use to refer to it:
- *
- * string_id = kdebug_trace_string(debugid, 0, "string");
- *
- * To replace a string previously traced:
- *
- * string_id = kdebug_trace_string(debugid, string_id, "new string");
- *
- * To invalidate a string ID:
- *
- * string_id = kdebug_trace_string(debugid, string_id, NULL);
- *
- * To check for errors:
- *
- * if ((int64_t)string_id == -1) { perror("string error") }
- *
- * @param debugid
- * The `debugid` to check if its enabled before tracing and include as
- * an argument in the event containing the string.
- *
- * Some classes or subclasses are reserved for specific uses and are not
- * allowed to be used with this function. No function qualifiers are
- * allowed on `debugid`.
- *
- * @param str_id
- * When 0, a new ID will be generated and returned if tracing is
- * enabled.
- *
- * Otherwise `str_id` must contain an ID that was previously generated
- * with this function. Clents should pass NULL in `str` if `str_id`
- * is no longer in use. Otherwise, the string previously mapped to
- * `str_id` will be overwritten with the contents of `str`.
- *
- * @param str
- * A NUL-terminated 'C' string containing the characters that should be
- * traced alongside `str_id`.
- *
- * If necessary, the string will be truncated at an
- * implementation-defined length. The string must not be the empty
- * string, but can be NULL if a valid `str_id` is provided.
- *
- * @return
- * 0 if tracing is disabled or `debugid` is being filtered out of trace.
- * It can also return (int64_t)-1 if an error occured. Otherwise,
- * it returns the ID to use to refer to the string in future
- * kdebug_trace(2) calls.
- *
- * The errors that can occur are:
- *
- * EINVAL
- * There are function qualifiers on `debugid`, `str` is empty, or
- * `str_id` was not generated by this function.
- * EPERM
- * The `debugid`'s class or subclass is reserved for internal use.
- * EFAULT
- * `str` is an invalid address or NULL when `str_id` is 0.
