NAME¶

iob_bytesleft - how many bytes are still to be sent?

SYNTAX¶

#include <libowfat/iob.h>

uint64 iob_bytesleft(const io_batch* b);

DESCRIPTION¶

iob_bytesleft returns the number of bytes that still need to be sent in this IO batch. If you just want to see whether you need to call iob_send again, there is no advantage in this function to calling iob_send directly and looking whether it returned 0.

SEE ALSO¶

iob_send(3)
