dc_context_new —
create a new device-handling context
library “libdivecomputer”
#include
<libdivecomputer/context.h>
dc_status_t
dc_context_new(
dc_context_t
**context);
Create a context in which dive computers may be queried. The
“context” supplies logging messages and so on, and may be
re-used for multiple dive computer query sessions. It is usually passed to
dc_device_open(3) to
query a specific dive computer device.
On success, the context must be freed with
dc_context_free(3).
You may configure the context with
dc_context_set_loglevel(3)
and
dc_context_set_logfunc(3).
This is highly recommended as the default logging behaviour of
dc_context_new depends upon compile-time
values.
This returns
DC_STATUS_OK on success, in
which case
context is filled in, or an error
code on failure.
