o Fixed `nfrontp' calculations in output_data(). If `remaining' is initially zero, it was possible for `nfrontp' to be decremented. Noticed by: dillon o Replaced leaking writenet() with output_datalen(): : * writenet : * : * Just a handy little function to write a bit of raw data to the net. : * It will force a transmit of the buffer if necessary : * : * arguments : * ptr - A pointer to a character string to write : * len - How many bytes to write : */ : void : writenet(ptr, len) : register unsigned char *ptr; : register int len; : { : /* flush buffer if no room for new data) */ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : if ((&netobuf[BUFSIZ] - nfrontp) < len) { : /* if this fails, don't worry, buffer is a little big */ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : netflush(); : } : : memmove(nfrontp, ptr, len); : nfrontp += len; : : } /* end of writenet */ What an irony! :-) o Optimized output_datalen() a bit. |
