Synopsis

Inquire about a display setting.

Syntax

MIL_INT MdispInquire(

MIL_ID DisplayId,	//in
MIL_INT64 InquireType,	//in
void *UserVarPtr	//out

)

Description

This function inquires about a specified display setting.

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see which MIL system’s documentation you should use in its place and any possible differences.

Parameters

This function is not supported on the selected boards.

This function reference has not been updated for the selected MIL system. To show the content of this page, choose a second MIL system; refer to the MIL system's release note to see which MIL system’s documentation to choose and any possible differences.

Parameters

DisplayId

Specifies the identifier of the display.

InquireType

Specifies the type of display setting about which to inquire.

See the Parameter associations section for possible values that can be specified.

UserVarPtr

Accepts the address of one of the following (see the Parameter associations section for specifics on which is expected):

array of type MIL_TEXT_CHAR
MIL_DOUBLE
MIL_ID
MIL_INT
MIL_INT64
MIL_WINDOW_HANDLE

Specifies the address in which to write the requested information. Since the MdispInquire() function also returns the requested information, you can set this parameter to M_NULL.

See the Parameter associations section for possible values that can be returned.

Parameter associations

The tables below list possible values for the InquireType parameter and possible values returned to the UserVarPtr parameter.

For all types of displays
For windowed, exclusive, and auxiliary displays

Remark

[MIL-Lite]

Note that during development and at runtime, compression support requires the presence of a MIL license that grants access to the compression/decompression package. This access is only granted by default with the development license dongle for the full version of MIL. In other cases, you must purchase access to this package separately.
