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:

file

The source file where the message was raised.

line

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

userdata

Return Values

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