* String Operation Attributes:

* These attributes are used with the XNVCTRLStringOperation()

* function; a string is specified as input, and a string is returned

* as output.

* Unless otherwise noted, all attributes can be operated upon using

* an NV_CTRL_TARGET_TYPE_X_SCREEN target.

* NV_CTRL_STRING_OPERATION_GVI_CONFIGURE_STREAMS - Configure the

streams-

* to-jack+channel topology for a GVI (Graphics capture board).

* The string input to GVI_CONFIGURE_STREAMS may be NULL. If this is

the

* case, then the current topology is returned.

* If the input string to GVI_CONFIGURE_STREAMS is not NULL, the string

* is interpreted as a semicolon (";") separated list of comma-

separated

* lists of "option=value" pairs that define a stream's composition.

The

* available options and their values are:

* "stream": Defines which stream this comma-separated list

describes.

* Valid values are the integers between 0 and

* NV_CTRL_GVI_NUM_STREAMS-1 (inclusive).

* "linkN": Defines a jack+channel pair to use for the given link N.

* Valid options are the string "linkN", where N is an

integer

* between 0 and NV_CTRL_GVI_MAX_LINKS_PER_STREAM-1

(inclusive).

* Valid values for these options are strings of the form

* "jackX" and/or "jackX.Y", where X is an integer between

0 and

* NV_CTRL_GVI_NUM_JACKS-1 (inclusive), and Y (optional) is

* integer between 0 and NV_CTRL_GVI_MAX_CHANNELS_PER_JACK-

* (inclusive).

* An example input string might look like:

1 2 ... 129 130 131 132 133 134 135 136 137 138 139 ... 146 147
