Set the logging function
logfunc associated
with a dive computer context. The logging function is invoked with argument
userdata when the log level (see
dc_context_set_loglevel(3))
has been exceeded.
The
logfunc accepts the following values:
-
-
- context
- The context in which it was invoked.
-
-
- 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
- The log message itself.
-
-
- userdata
- The pointer passed to
dc_context_set_logfunc.
Returns
DC_STATUS_OK on setting the log
level,
DC_STATUS_INVALIDARGS if
context is
NULL, or another error code on failure.
