Dear Sir:
I call sosend occur error. The error code=3D22.
What wrong in my code?
The code follow:
socreate(); file://is ok;
|
}
top=3Dm_get(MT_DATA,M_DONTWAIT);
if(top=3D=3DNULL)
{
log(LOG_INFO, "top=3DNULL occur error\n");
goto out;
}
top->m_next=3DNULL;
top->m_nextpkt=3DNULL;
top->m_len=3D50;
adr=3Dsizeof(struct m_hdr) +sizeof(int)+sizeof(struct ifnet *);
log(LOG_INFO, "adr=3D %d \n",adr);
top->m_data=3Dtop+adr;
log(LOG_INFO, "top=3D %x, top->m_data=3D %x,top+adr=3D%x \n",top=20
,top->m_data,top+adr);
top->m_type=3DMT_DATA;
top->m_flags=3DM_PKTHDR;
top->m_pkthdr.len=3D50;
top->m_pkthdr.rcvif=3DNULL;
log(LOG_INFO, "top=3D %x, Data=3D %x \n",top ,top->m_data);
error =3D sosend(so,(struct sockaddr *) &sin,NULL,top,=20
0,MSG_DONTROUTE);
Thanks/regards
