OPEN DISPLAY

OpenVMS Format

display_return = X$OPEN_DISPLAY

([display_name])

Argument Information
Argument Usage Data Type Access Mechanism
display_return identifier uns longword write value
display_name char_string character string read descriptor

Arguments

display_name

The name of the hardware display to which you want to connect. The display_name argument is a string that has the following format:

hostname::number.screen

The string elements are as follows:
hostname The name of the host machine to which the display is physically connected. Specify zero if the client program and the server are running in the same CPU.
number The number of the server on that host machine. A single CPU can have one or more servers, which are usually numbered starting with zero.
screen The number of the screen on that server. An X server can control multiple screens on one display. The screen sets an internal variable that can be accessed by using the DefaultScreen macro or the DEFAULT SCREEN function.

The display_name argument, which is optional, is the address of the character string descriptor that points to the string. If you omit the display_name argument, the OPEN DISPLAY routine translates the logical name DECW$DISPLAY to find the display name.

Argument Information
Argument Usage Data Type Access Mechanism
status_return cond_value uns longword write value

colormap_id identifier uns longword read reference
color_name char_string character string read descriptor
screen_def_return record x$color write reference

Returns

status_return

Specifies whether the routine completed successfully. PARSE COLOR returns one of the following values:
Value Description
SS$_NORMAL Routine completed successfully.
X$_ERRORREPLY Error received from server.

Arguments

color_name

The name of the color. The string can be either a color name string or a numeric specification. If you use a text string, the name must be supported by the color database maintained by the server. See the SYS$MANAGER:DECW$RGB.COM file for a list of all named colors. Case is not significant.

The color_name argument is the address of a character string descriptor that points to the string.
