Name
netbuf_copy() — Copy all netbuf data to memory pointer
Synopsis
void netbuf_copy
(struct netbuf *buf
, void *data
, u16_t len
);
Description
Copies all of the data from the netbuf buf into the
memory pointed to by data even if the netbuf buf is
fragmented. The len parameter is an upper bound of
how much data that will be copied into the memory pointed to by data.
Example
Example 164.4. This example shows a simple use of netbuf_copy()
Here, 200 bytes of memory is allocated on the stack to hold data. Even if
the netbuf buf has more data that 200 bytes, only 200 bytes are copied into
data.

netbuf_copy(buf, data, 200);
/* do something with the data */
