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

Note: Many $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.
  • 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:

    String Matches
    C*D CUSTID or COD or CLOD
    S??T SALT or SLOT or SORT
    E"*CONCRETE E*CONCRETE

Examples

  1. The following program unbinds the resource called "SMITHERS".

    b %rc = $Unbind( 'SMITHERS' ) End

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

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