.SH "NAME"
ibv_gid_reachable \- will contact the SA to do a path record lookup from the
device,port specified by 'context','port' to the remote 'gid_p'.  It finds the
status of the remote GID (reachable or unreachable).

.TP
.B gid_p
A pointer to the gid to check
.TP
.B context
A device context obtained from a call to ibv_open_device().
This identifies the device to use in order to contact the
remote 'gid_p'.
.TP
.B port
Specifies the port on the device associated with 'context'.
If '0' then the implementation will choose a port.
.TP
.B timeout
It is currently set to '0' and reserved for future enhancement.
ibv_gid_reachable() will block until a response
(success, fail or no path found) is obtained.
