DC_DEVICE_FOREACH(3) Library Functions Manual DC_DEVICE_FOREACH(3)

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_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).
