Detailed Description

Setup routines used to construct UVC access contexts.

Function Documentation

uvc_init()

uvc_error_t uvc_init	(	uvc_context_t **	pctx,
		struct libusb_context *	usb_ctx
	)

Initializes the UVC context.

Note

If you provide your own USB context, you must handle libusb event processing using a function such as libusb_handle_events.

Parameters

[out]	pctx	The location where the context reference should be stored.
[in]	usb_ctx	Optional USB context to use

Returns

Error opening context or UVC_SUCCESS

uvc_exit()

void uvc_exit

(

uvc_context_t *

ctx

)

Closes the UVC context, shutting down any active cameras.

Note

This function invalides any existing references to the context's cameras.

If no USB context was provided to uvc_init, the UVC-specific USB context will be destroyed.

Parameters

ctx	UVC context to shut down
