.SH MEMBER FUNCTION DOCUMENTATION
.PP
.SS void ACE_RW_Thread_Mutex::dump (void) const
.PP
Dump the state of an object.
.PP
Reimplemented from \fBACE_RW_Mutex\fR.
.SS int ACE_RW_Thread_Mutex::tryacquire_write_upgrade (void)
.PP
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).
.PP
Reimplemented from \fBACE_RW_Mutex\fR.
.SH MEMBER DATA DOCUMENTATION
.PP
.SS ACE_RW_Thread_Mutex::ACE_ALLOC_HOOK_DECLARE
.PP
Declare the dynamic allocation hooks.
