.SH "NAME"
wimax_msg_send \- Send a pre\-allocated message to user space
.SH "SYNOPSIS"
.HP \w'int\ wimax_msg_send('u
.BI "int wimax_msg_send(struct\ wimax_dev\ *\ " "wimax_dev" ", struct\ sk_buff\ *\ " "skb" ");"
.SH "ARGUMENTS"
.PP
\fIwimax_dev\fR
.RS 4
WiMAX device descriptor
.RE
.PP
\fIskb\fR
.RS 4
struct sk_buff
returned by
\fBwimax_msg_alloc\fR\&. Note the ownership of
\fIskb\fR
is transferred to this function\&.
.RE
.SH "RETURN"
.PP
0 if ok, < 0 errno code on error
.SH "DESCRIPTION"
.PP
.PP
Sends a free\-form message that was preallocated with
\fBwimax_msg_alloc\fR
and filled up\&.
.PP
Assumes that once you pass an skb to this function for sending, it owns it and will release it when done (on success)\&.
.PP
IMPORTANT:
.PP
Don\*(Aqt use
\fBskb_push\fR/\fBskb_pull\fR/\fBskb_reserve\fR
on the skb, as
\fBwimax_msg_send\fR
depends on skb\->data being placed at the beginning of the user message\&.
.PP
Unlike other WiMAX stack calls, this call can be used way early, even before
\fBwimax_dev_add\fR
is called, as long as the wimax_dev\->net_dev pointer is set to point to a proper net_dev\&. This is so that drivers can use it early in case they need to send stuff around or communicate with user space\&.
