Return list of bound semaphores onto a $list
Note: Many $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:
Offset Contents 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
matchesCUSTID
,COD
orCLOD
.S??T
matchesSALT
,SLOT
orSORT
.E"*CONCRETE
matchesE*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')
