mutex.h
Mutex for thread synchronization.
gnrc_pktbuf_contains
bool gnrc_pktbuf_contains(void *ptr)
Check if the given pointer is indeed part of the packet buffer.
gnrc_pktbuf_mutex
mutex_t gnrc_pktbuf_mutex
Mutex used to provide mutually exclusive access to packet buffer data structures.
gnrc_pktbuf_is_sane
bool gnrc_pktbuf_is_sane(void)
Checks if the implementation's internal invariants still uphold.
gnrc_pktbuf_is_empty
bool gnrc_pktbuf_is_empty(void)
Checks if packet buffer is empty.
gnrc_pktbuf_free_internal
void gnrc_pktbuf_free_internal(void *data, size_t size)
Release an internal buffer.
mutex_t
Mutex structure.
