2 * This header file defines the interface to our reader function for
3 * hexadecimal RTP frame sequence files in TW-TS-005 format.
4 *
5 * twts005_read_frame() return values are:
6 * 1 = successfully read valid frame
7 * 0 = normal EOF
8 * -1 = read line with invalid content
9 * -2 = line too long or missing newline
10 *
11 * The reader function skips blank, whitespace-only and comment lines,
12 * returning only actual frames. lineno variable must be initialized to 0
13 * by the application program, but not touched otherwise. In case of an
14 * error, this variable will hold the line number at which the error was
15 * encountered.
