$Unbind and $UnbindW

$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.

Syntax

%result = $Unbind(res_name)

%result = $UnbindW(res_name)

Syntax terms

%result	A status code that indicates the result of the function.
res_name	The name of the resource to be unbound. This resource name can be any string up to 255 bytes long.

Status codes

For $Unbind:

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

For $UnbindW:

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

Usage notes

• 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.

Examples

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
