Data Fields
int(*)	write (void *ctx, const void *data, size_t len)
	Returns bytes written, or a negative value on failure.
bool(*)	flush (void *ctx)
	Commit what has been written, so that a power cut keeps it.
void *	ctx

Detailed Description

The byte sink a log writer writes to, with its commit.

Field Documentation

flush

bool(*) log_sink_t::flush(void *ctx)

Commit what has been written, so that a power cut keeps it.

NULL for a sink that needs no commit, such as memory. Returns false on failure. Writing a row is not keeping it: on FAT (file allocation table) the directory entry carries the length, and until that entry is written the file reads as 0 bytes whatever the data sectors hold.
