function LeaseBlob(const ContainerName: String; const BlobName: String; const LeaseAction: String = 'acquire';
const LeaseId: String = ''): String;

C++

System::UnicodeString __fastcall LeaseBlob(const System::UnicodeString ContainerName, const System::UnicodeString BlobName, const System::UnicodeString LeaseAction = L"acquire", const System::UnicodeString LeaseId = System::UnicodeString());

Description

Acquires a lock on the given blob for write access.

LeaseBlob acquires a one-minute lock on the given blob, if the LeaseAction parameter has the acquire value (by default).

Other available actions for LeaseAction are:

Value	Meaning
acquire	Acquires a one minute lock.
renew	Extends the lock for an additional minute.
release	Immediately releases the lock.
break	Releases the lock after the end of its minute, so that anyone can call it with no LeaseId.

Note: renew and release both require a LeaseId to perform.

Note: After break is called, until the lock is released and a new lease is acquired, renew cannot be called on the blob.
