Every platform should decide which implementation for read/write locks |
// Select the read-write-lock implementation for your platform: |
should be used in OpenPegasus by defining one of the following: |
// |
1.) PEGASUS_USE_POSIX_RWLOCK - POSIX standard based implementation |
// PEGASUS_USE_POSIX_RWLOCK |
2.) PEGASUS_USE_SEMAPHORE_RWLOCK - mutex based implementation |
// PEGASUS_USE_SEMAPHORE_RWLOCK |
|
// |
The definition for each platform can be found in the according platform |
