SYNOPSIS

#include <libdivecomputer/context.h>

typedef void
(*dc_logfunc_t)(dc_context_t *context, dc_loglevel_t loglevel, const char *file, unsigned int line, const char *function, const char *message, void *userdata);

dc_status_t
dc_context_set_logfunc(dc_context_t *context, dc_logfunc_t logfunc, void *userdata);

The logfunc accepts the following values:

context

loglevel

The level of the log message.

file

The source file where the message was raised.

line

The source line (from 1) where the message was raised.

function

The function that raised the log message.

message

userdata

The pointer passed to dc_context_set_logfunc.

RETURN VALUES

Returns DC_STATUS_OK on setting the log level, DC_STATUS_INVALIDARGS if context is NULL, or another error code on failure.
