NAME

       umad_send - send umad

SYNOPSIS

       #include <infiniband/umad.h>

       int umad_send(int portid, int agentid, void *umad, int length, int timeout_ms, int retries);

DESCRIPTION

       umad_send()  sends  length bytes from the specified umad buffer from the port specified by
       portid, and using the agent specified by agentid.  timeout_ms controls the solicited  MADs
       behavior  as follows: zero value means not solicited. Positive value makes kernel indicate
       timeout in milliseconds. If reply is not received within the specified value, the original
       buffer  is  returned in the read channel with the status field set (to non zero). Negative
       timeout_ms makes kernel wait forever for the reply.  retries indicates the number of times
       the MAD will be retried before giving up.

RETURN VALUE

       umad_send() returns 0 on success, and a negative value on error as follows:
        -EINVAL invalid port handle or agentid
        -EIO    send operation failed
