$Unbind and $UnbindW: Unbind resource previously bound via $Bind

Most Sirius $functions have been deprecated in favor of Object Oriented methods. There are no OO equivalents for the $Unbind and $UnbindW functions.

The $Unbind and $UnbindW functions unbind resources previously bound with the $Bind function. Use $UnBind to unbind a single resource. Use $UnBindW to unbind a set of resources specified with wildcards.

$Unbind and $UnbindW accept one argument and return a numeric code.

The only argument is the name of the resource to be unbound. This resource name can be any string up to 255 bytes long.

Syntax

<section begin="syntax" />%result = $Unbind(res_name) <section end="syntax" />

$Unbind Function

%RESULT is set to indicate the success of the function.

0 - Resource successfully unbound 1 - Resource name missing 2 - User does not have resource bound

$Unbind return codes

%RESULT = $UnbindW(res_name)

$UnbindW Function

%RESULT is set to indicate the number of unbound semaphores.

N - The number of unbound semaphores All other errors cause request cancellation

$UnbindW return codes

A resource remains bound until it is either explicitly unbound with the $Unbind or $UnbindW function or the binding user logs off or is restarted.

The following program unbinds the resource called "SMITHERS".

B %RC = $Unbind( 'SMITHERS' ) END


The semaphore name specified as the argument to $UnbindW can be an explicit name or it can contain the following wildcard characters:

* Matches any number of characters including none
? Matches any single character
" Indicates that the next character must be treated literally, even if it is a wildcard character.

For example:

d.This string ... d.Matches ...
C*D CUSTID or COD or CLOD
S??T SALT or SLOT or SORT
E"*CONCRETE E*CONCRETE

The following program unbinds the all resource that begin with the letters "SMITH".

B %RC = $UnbindW( 'SMITH*' ) END
