[Tremor] Byte order problem

[Niklas Barsk]

Hi,

I tried using ntohs and ntohl on the buffer from ov_read() but it does
not do anything with its content. I have not found any good examples
of how to use ntohl so I might use it the wrong way. This is what I
tried to do right after the ov_read() (buf contains the read data):

{
int i;
for( i = 0; i < buflen; ++i)
 buf[i] = htonl( buf[i] );
}

Best regards
Niklas Barsk
