static _go32_dpmi_seginfo pktout;
static unsigned char sendbuf[64];

void main (etc...

        pktout.size=(16*1024L+15)/16;
        _go32_dpmi_allocate_dos_memory(&pktout);

        dosmemput(sendbuf,60,pktout.rm_segment*16);

this snippet of code causes all number of weird problems for me.
when i use dosmemput as above is correctly copies the contents of sendbuf
into dos memory, but tends to corrupt memory and cause an emm fault at the
same time. if i use &sendbuf it doesn't cause any problems - but doesn't
copy the buffer either ;( presumably i've made some silly mistake here but
i can't see it - can anyone else spot the bug?

regards,
nik
