Detailed Description

Wrapper for readers/writer locks that exist within a process.


Constructor & Destructor Documentation

ACE_RW_Thread_Mutex::ACE_RW_Thread_Mutex const ACE_TCHAR   name = 0,
void *    arg = 0
 

ACE_RW_Thread_Mutex::~ACE_RW_Thread_Mutex void   
 

Default dtor.


Member Function Documentation

void ACE_RW_Thread_Mutex::dump void    const
 

Dump the state of an object.

Reimplemented from ACE_RW_Mutex.

int ACE_RW_Thread_Mutex::tryacquire_write_upgrade void   
 

Conditionally upgrade a read lock to a write lock.

This only works if there are no other readers present, in which case the method returns 0. Otherwise, the method returns -1 and sets <errno> to <EBUSY>. Note that the caller of this method *must* already possess this lock as a read lock (but this condition is not checked by the current implementation).

Reimplemented from ACE_RW_Mutex.


Member Data Documentation

ACE_RW_Thread_Mutex::ACE_ALLOC_HOOK_DECLARE
