- * @param logdomain The string to use as logdomain for libsigrokdecode log
- * messages from now on. Must not be NULL. The maximum
- * length of the string is 30 characters (this does not
- * include the trailing NUL-byte). Longer strings are
- * silently truncated.
- * In order to not use a logdomain, pass an empty string.
- * The function makes its own copy of the input string, i.e.
- * the caller does not need to keep it around.
- * @return SRD_OK upon success, SRD_ERR_ARG upon invalid logdomain.
