UMAD_SEND(3)						    OpenIB Programmer's Manual						      UMAD_SEND(3)

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
