Summary
Enters the critical section.
Pascal
public procedure Enter;
Description
Enter attempts to get access to the critical section, this is referred to as acquiring ownership of the critical section. Only one thread can own the critical section at any time. If the critical section is currently owned by a different thread the function blocks until the critical section becomes free. After acquiring ownership of the critical section you must release it as soon as you are done with it by calling the Leave method. Although only one thread can own the critical section, a single thread can own the critical section more than once. This means you can call Enter multiple times. However, calls to Enter and Leave must be balanced: you must call Leave for each time you call Enter.

Notes
In extremely low-memory situations a call to Enter may fail by raising an exception. If you cannot tolerate a failure of Enter you should use TJclCriticalSectionEx instead.
