Parameters

timeout

Type: guint64

Acquisition timeout in µs. Zero means no timeout.

error

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

A new ArvBuffer, NULL on error. The returned buffer must be freed using g_object_unref().

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
