If the specified dl_ack_thresh is greater than the remote receive
window size, then a DL_ERROR_ACK with dl_errno set to
DL_SYSERR and dl_unix_errno set to EINVAL is returned.
The UNIX error returned may be set to (not limited to) errors listed
in Table 2-2 on page 71.
DL_HP_SET_LOCAL_WIN_REQ
Requests the DLS provider to set the local window size to the specified
value.
NOTE
Setting the local window size also causes the DLPI read side streams
queue hi water mark to be set to (local_window_size * MTU). The
(local_window_size * MTU) cannot exceed (1 << 16) - (2 * MTU).
Format
typedef struct {
u_long
dl_primitive;
u_long
dl_local_win;
} dl_hp_set_local_win_req_t;
Parameters
dl_primitive
DL_HP_SET_LOCAL_WIN_REQ
dl_local_win
size of the local receive window. This value must be greater than 0
and less than 128.
State
The message is valid in the states DL_IDLE, DL_DATAXFER,
DL_OUTCON_PENDING, DL_INCON_PENDING,
DL_USER_RESET_PENDING, and DL_PROV_RESET_PENDING.
New State
The resulting state is unchanged.
