A semaphore is defined in the dictionary as a system of signaling In the realm of threads, a semaphore can be used to indicate a particular occurrence to a thread The information is provided in the form of a number, and this number can be increased or decreased as necessary The method for employing the semaphore is to use the Thread::Semaphore module and create a new object:

Table 182 summarizes the different roles that can be assigned to users and groups over a public folder

$sema = new Thread::Semaphore;

set doc_opening to move end of range doc_opening by a paragraph item count -2

The default value is 1, or you can specify the initial value:

$sema = new Thread::Semaphore(256);

Two methods, up and down, then increase or decrease the value, either by the default value of 1, or by the amount specified The lowest value however is 1, so the code

User has no access to the folder, but the folder is visible in the folder list on the client (unless the folder has been hidden by the administrator) User can create new items in the folder but cannot read existing ones or view the contents of the folder User can read existing items in the folder and view the folder s contents but cannot create new items or modify existing ones User can create new items and read existing ones in the folder but cannot modify any items (even ones they create); however, users can delete their own posted items User can create new items and edit them, view existing items but not edit them, and delete his or her own posted items Like the Author role except that the user can also create new subfolders within the folder Like the Author role except that the user can also edit or delete other people s posted items Like the Publishing Author role except that the user can also edit or delete other people s posted items User can do anything with the folder except delete the folder itself

The following statement uses the create range command to redefine the doc_opening range to the position before the first character of the document Here, the create range command takes a direct parameter (active document) specifying the document, a start parameter specifying the start position (character position 0), and an end parameter specifying the end position (also character position 0, making the range a single point right at the beginning of the document)

$sema->up; $sema->down(256);
