* "stream=0, link0=jack0, link1=jack1; stream=1, link0=jack2.1"

* This example specifies two streams, stream 0 and stream 1. Stream

* is defined to capture link0 data from the first channel (channel

0) of

* BNC jack 0 and link1 data from the first channel of BNC jack 1.

The

* second stream (Stream 1) is defined to capture link0 data from

channel 1

* (second channel) of BNC jack 2.

* This example shows a possible configuration for capturing 3G input:

* "stream=0, link0=jack0.0, link1=jack0.1"

* Applications should query the following attributes to determine

* possible combinations:

* NV_CTRL_GVI_MAX_STREAMS

* NV_CTRL_GVI_MAX_LINKS_PER_STREAM

* NV_CTRL_GVI_NUM_JACKS

* NV_CTRL_GVI_MAX_CHANNELS_PER_JACK

* Note: A jack+channel pair can only be tied to one link/stream.

* Upon successful configuration or querying of this attribute, a

string

* representing the current topology for all known streams on the

device

* will be returned. On failure, NULL is returned.

#define NV_CTRL_STRING_OPERATION_GVI_CONFIGURE_STREAMS 4 /* RW-

I */

* CTRLAttributeValidValuesRec -

* structure and related defines used by

* XNVCTRLQueryValidAttributeValues() to describe the valid values of

* a particular attribute. The type field will be one of:

* ATTRIBUTE_TYPE_INTEGER : the attribute is an integer value; there

* is no fixed range of valid values.

* ATTRIBUTE_TYPE_BITMASK : the attribute is an integer value,

* interpretted as a bitmask.

* ATTRIBUTE_TYPE_BOOL : the attribute is a boolean, valid values are
