Function Documentation

◆ gnrc_sixlowpan_frag_fb_get()

gnrc_sixlowpan_frag_fb_t * gnrc_sixlowpan_frag_fb_get ( void )

Allocates a fragmentation buffer entry.

Returns: A fragmentation buffer entry if available; NULL, otherwise

◆ gnrc_sixlowpan_frag_fb_get_by_tag()

gnrc_sixlowpan_frag_fb_t * gnrc_sixlowpan_frag_fb_get_by_tag ( uint16_t tag )

Get an existing fragmentation buffer entry by a given tag.

Parameters

[in] tag Tag to search for.

Returns: a fragmentation buffer entry if one with tag exists.; NULL, if no fragmentation buffer entry can be found.

◆ gnrc_sixlowpan_frag_fb_next_tag()

uint16_t gnrc_sixlowpan_frag_fb_next_tag ( void )

Generate a new datagram tag for sending.

Returns: A new datagram tag.

◆ gnrc_sixlowpan_frag_fb_reset()

void gnrc_sixlowpan_frag_fb_reset ( void )

Reset fragmentation buffer.

Note: Only available with test

◆ gnrc_sixlowpan_frag_fb_send()

static bool gnrc_sixlowpan_frag_fb_send ( gnrc_sixlowpan_frag_fb_t * fbuf )

inlinestatic

Sends a message to pass a further fragment down the network stack.

See also: GNRC_SIXLOWPAN_MSG_FRAG_SND

Parameters

[in] fbuf A fragmentation buffer entry ]

Returns: true, when the message was sent; false when sending the message failed.
