Is this a bug? return (packet_buffer_packet_t *) &p_buffer->buffer[index];

[zzzh]

below is a little part of code copied from nrf5_SDK_for_Mesh_v2.2.0_src:

************************************************************************************************************************

static inline packet_buffer_packet_t * m_get_packet(const packet_buffer_t * p_buffer, uint16_t index)
{
return (packet_buffer_packet_t *) &p_buffer->buffer[index]; 
}

*************************************************************************************************************************

buffer is defined as uint8_t *, how can it be packet_buffer_packet_t *?

Is this a bug?

seems there's another bug close to this:

 p_first_packet->size = p_buffer->size - sizeof(packet_buffer_packet_t);

Hi,

No, this is not a bug. Packet buffer data structure `packet_buffer_t` contains a pointer to the memory buffer (`buffer`). Individual packets of `packet_buffer_packet_t` type are allocated inside this memory pool.

Hi, Mttrinh,

I guess you are right, I saw it from packet_buffer_init, where have no context to understand it.

Busying on something else, will check this later..
