VMS Help TCPIP Services, Programming Interfaces, Sockets API, recv()  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    user-provided buffer.
    The $QIO equivalent is the IO$_READVBLK function.
    Format
      #include  <types.h>
      #include  <socket.h>
      int recv  ( int s, char *buf, int len, int flags );
