.Os
.Sh NAME
.Nm dc_context_new
.Nd create a new device-handling context
.Sh LIBRARY
.Lb libdivecomputer
.Sh SYNOPSIS
.In libdivecomputer/context.h
.Ft dc_status_t
.Fo dc_context_new
.Fa "dc_context_t **context"
.Fc
.Sh DESCRIPTION
Create a context in which dive computers may be queried.
The
.Dq context
supplies logging messages and so on, and may be re-used for multiple
dive computer query sessions.
It is usually passed to
.Xr dc_device_open 3
to query a specific dive computer device.
.Pp
On success, the context must be freed with
.Xr dc_context_free 3 .
You may configure the context with
.Xr dc_context_set_loglevel 3
and
.Xr dc_context_set_logfunc 3 .
This is highly recommended as the default logging behaviour of
.Nm
depends upon compile-time values.
.Sh RETURN VALUES
This returns
.Dv DC_STATUS_OK
on success, in which case
.Fa context
is filled in, or an error code on failure.
