Return list of bound semaphores onto a $list

Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $Bind_List function.

This function retrieves semaphores bound with $Bind by a specific or all users.

The $Bind_List function accepts three arguments and returns a number indicating the success of the function.

Syntax

%rc = $Bind_List(olist, [sem_name], [user_num])

Syntax terms

%rc The number of items added to olist, or a negative (error) return code.
olist The output $list identifier. If the output $list is not empty, data is added to the end of the $list. See "Usage notes" for the $list format.
sem_name The name of the semaphore for which information is to be returned. This value can be a single specific semaphore name, or it can be a wildcard string that matches a number of semaphores. The argument default value is asterisk (*), which means to return all semaphores bound by all users or by a specific user.
user_num The user number of the user for which bound semaphores are to be returned. This optional argument defaults to -1, which means return semaphores bound by all users.

Return codes

>=0 Number of bound semaphores returned
-3 $list full or out of CCATEMP

All other errors result in request cancellation


Usage notes

  • The format of the olist output $list is shown below:
    OffsetContents
    0-4 The user number of the user that has the semaphore bound represented as a string with leading zeros included.
    5-14 The userid of the user that has the semaphore bound represented as a string padded with trailing blanks.
    15-end The name of the bound semaphore.
  • The semaphore name specified in the second argument 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:

    C*D matches CUSTID, COD or CLOD.
    S??T matches SALT, SLOT or SORT.
    E"*CONCRETE matches E*CONCRETE.

Example

The following code fragment retrieves all semaphores bound by the current user where the semaphore name ends with the letters _TEMP into a $list and sorts the $list by semaphore name.

%rc = $Bind_List(%olist, '*_TEMP', $USER) %slist = $ListSort(%olist, '16,255, A')
