net_buf_skip() function

Network buffer.

Total length of data to be skipped.

Get a pointer to the user data of a buffer.

Put a buffer into a list Put a buffer to the end of a list. If the buffer contains follow-up fragments this function will take care of inserting them as well into the list.

Increment the reference count of a buffer.

Find the last fragment in the fragment list.

Get a zero-based index for a buffer. This function will translate a buffer into a zero-based index, based on its placement in its buffer pool. This can be useful if you want to associate an external array of meta-data contexts with the buffers of a pool.

Reset buffer Reset buffer data and flags so it can be reused for other purposes.

Insert a new fragment to a chain of bufs. Insert a new fragment into the buffer fragments list after the parent. Note: This function takes ownership of the fragment reference so the caller is not required to unref.

Add a new fragment to the end of a chain of bufs. Append a new fragment into the buffer fragments list. Note: This function takes ownership of the fragment reference so the caller is not required to unref.

Copy bytes from net_buf chain starting at offset to linear buffer Copy (extract) @a len bytes from @a src net_buf chain, starting from @a offset in it, to a linear buffer @a dst. Return number of bytes actually copied, which may be less than requested, if net_buf chain doesn't have enough data, or destination buffer is too small.

Append data to a list of net_buf Append data to a net_buf. If there is not enough space in the net_buf then more net_buf will be added, unless there are no free net_buf and timeout occurs.

Calculate amount of bytes stored in fragments. Calculates the total amount of data stored in the given buffer and the fragments linked to it.
