dc_device_foreach
—
iterate over dives in a dive computer
library “libdivecomputer”
#include
<libdivecomputer/device.h>
typedef int
(*dc_dive_callback_t)
(const unsigned
char *data, unsigned int size,
const unsigned char *fingerprint,
unsigned int fsize, void
*userdata);
dc_status_t
dc_device_foreach
(dc_device_t
*device, dc_dive_callback_t callback,
void *userdata);
Iterate over all dives on device by calling callback with userdata.
Each dive invokes callback with the dive data, which should be parsed with dc_parser_set_data(3), and the binary fingerprint of the dive. The fingerprint can be used to record the newest dive and stop processing (on subsequent invocations) when the same dive fingerprint is encountered.
The callback function must return non-zero to continue downloading dives, or zero to stop.
This returns DC_STATUS_SUCCESS
on success
or one of several error values on error. If callback
returns zero, this will not be reflected in the return value (usually
DC_STATUS_SUCCESS
).
