Function Documentation
◆ gnrc_pktbuf_contains()
| bool gnrc_pktbuf_contains | ( | void * | ptr | ) |
Check if the given pointer is indeed part of the packet buffer.
- Warning
- This function is internal.
- Parameters
-
ptr pointer to check
- Return values
-
true It is plausible, that this pointer belongs to data in the packet buffer false ptrdoes not point to data in the packet buffer
◆ gnrc_pktbuf_free_internal()
| void gnrc_pktbuf_free_internal | ( | void * | data, |
| size_t | size | ||
| ) |
Release an internal buffer.
- Warning
- This function is internal. Use gnrc_pktbuf_release to release a packet buffer
- Parameters
-
data pointer to the internal buffer to release size size of datain bytes
◆ gnrc_pktbuf_is_empty()
| bool gnrc_pktbuf_is_empty | ( | void | ) |
Checks if packet buffer is empty.
- Returns
- true, if packet buffer is empty
- false, if packet buffer is not empty
◆ gnrc_pktbuf_is_sane()
| bool gnrc_pktbuf_is_sane | ( | void | ) |
Checks if the implementation's internal invariants still uphold.
- Returns
- true, the packet buffer is sane.
- false, the packet buffer is insane.
