sppAllAcked()

PROTOTYPE

#include <spp.h>

int sppAllAcked(void);

DESCRIPTION

sppAllAcked() checks if all previously sent data frames have been received (acknowledged) by the peer. If non-blocking mode has been set, sppAllAcked() returns immediately. Otherwise, the call blocks until all previously sent data frames are acknowledged or the link is reset.

If successful, sppAllAcked() returns 0. Otherwise, it sets errno and returns -1.

ERROR CODES

SPP_UNCONNECTED	The channel is unconnected.
SPP_UNINITIALIZED	The initialization routine sppInit() has not been called.
SPP_WOULD_BLOCK	API is non-blocking and unacknowledged data frames exist.
