Private Methods | |
ACE_Thread (void) | |
Ensure that we don't get instantiated. More... |
This class provides a common interface that is mapped onto POSIX Pthreads, Solaris threads, Win32 threads, VxWorks threads, or pSoS threads. Note, however, that it is generally a better idea to use the <ACE_Thread_Manager> programming API rather than the <ACE_Thread> API since the thread manager is more powerful.

Ensure that we don't get instantiated.
|
|
Cancel a thread. Note that this method is only portable on platforms, such as POSIX pthreads, that support thread cancellation. |
|
Disable thread cancellation.
|
|
Enable thread cancellation.
|
|
Exit the current thread and return "status". Should _not_ be called by main thread.

|
|
Get the priority of a particular thread.
|
|
Stores the current value bound to <key> for the calling thread into the location pointed to by <valuep>.

|
|
Send a signal to the thread.
|

|
|
Return the unique ID of the thread.
|
|
Return the unique kernel handle of the thread. Note that on Win32 this is actually a pseudohandle, which cannot be shared with other processes or waited on by threads. To locate the real handle, please use the <ACE_Thread_Manager::thr_self> method. |

Creates a new thread having <flags> attributes and running <func> with <args> (if <thread_adapter> is non-0 then <func> and <args> are ignored and are obtained from <thread_adapter>). <thr_id> and <t_handle> are set to the thread's ID and handle (?), respectively. The thread runs at <priority> priority (see below). The <flags> are a bitwise-OR of the following: = BEGIN<INDENT> THR_CANCEL_DISABLE, THR_CANCEL_ENABLE, THR_CANCEL_DEFERRED, THR_CANCEL_ASYNCHRONOUS, THR_BOUND, THR_NEW_LWP, THR_DETACHED, THR_SUSPENDED, THR_DAEMON, THR_JOINABLE, THR_SCHED_FIFO, THR_SCHED_RR, THR_SCHED_DEFAULT, THR_EXPLICIT_SCHED, THR_SCOPE_SYSTEM, THR_SCOPE_PROCESS = END<INDENT> By default, or if <priority> is set to ACE_DEFAULT_THREAD_PRIORITY, an "appropriate" priority value for the given scheduling policy (specified in <flags}>, e.g., <THR_SCHED_DEFAULT>) is used. This value is calculated dynamically, and is the median value between the minimum and maximum priority values for the given policy. If an explicit value is given, it is used. Note that actual priority values are EXTREMEMLY implementation-dependent, and are probably best avoided. Note that <thread_adapter> is always deleted when <spawn> is called, so it must be allocated with global operator new. |
|
Spawn <n> new threads, which execute <func> with argument <arg> (if <thread_adapter> is non-0 then <func> and <args> are ignored and are obtained from <thread_adapter>). The thread_ids of successfully spawned threads will be placed into the <thread_ids> buffer (which must be the same size as <n>). If <stack> != 0 it is assumed to be an array of <n> pointers to the base of the stacks to use for the threads being spawned. If <stack_size> != 0 it is assumed to be an array of <n> values indicating how big each of the corresponding <stack>s are. If <thread_handles> != 0 it is assumed to be an array of <n> thread_handles that will be assigned the values of the thread handles being spawned. Returns the number of threads actually spawned (if this doesn't equal the number requested then something has gone wrong and <errno> will explain...). See also <spawn>. |

Spawn N new threads, which execute <func> with argument <arg> (if <thread_adapter> is non-0 then <func> and <args> are ignored and are obtained from <thread_adapter>). If <stack> != 0 it is assumed to be an array of <n> pointers to the base of the stacks to use for the threads being spawned. Likewise, if <stack_size> != 0 it is assumed to be an array of <n> values indicating how big each of the corresponding <stack>s are. Returns the number of threads actually spawned (if this doesn't equal the number requested then something has gone wrong and <errno> will explain...). See also <spawn>. |
