Hi

    Is there a way to read only the last message arrived (and flush the
file).

    For instance, a task receive a continous flow of the same data with a
specific tag and is only interested
in the last message. Doing a while pvm_recv will block the system because
the sender task send as much messages
as it can.

it can be done with socket with a code like that :

 ioctlsocket(sock,FIONREAD,&size);
 UnusedSize=size-sizeof(MyStruct);
 buf=malloc(UnusedSize);
 recv(sock,buf,UnusedSize,0);
 recv(sock,(char *)&MyStruct,sizeof(MyStruct),0);
 free (buf);

but with Pvm ?

    Any ideas ?

    Vincent
