# MutexDirect

from pandac.PandaModules import MutexDirect

Class : MutexDirect
Description : This class implements a standard mutex by making direct calls to the underlying implementation layer. It doesn't perform any debugging operations.

## Inheritance:

MutexDirect:

## Methods of MutexDirect:

debugIsLocked
lock
output
release

debugIsLocked bool MutexDirect::debug_is_locked(void) const; Description: Returns true if the current thread has locked the Mutex, false otherwise. This method is only intended for use in debugging, hence the method name; in the MutexDirect case, it always returns true, since there's not a reliable way to determine this otherwise.

lock void MutexDirect::lock(void) const; Description: Grabs the mutex if it is available. If it is not available, blocks until it becomes available, then grabs it. In either case, the function does not return until the mutex is held; you should then call unlock(). This method is considered const so that you can lock and unlock const mutexes, mainly to allow thread-safe access to otherwise const data. Also see MutexHolder.

output void MutexDirect::output(ostream &out) const; Description: This method is declared virtual in MutexDebug, but non-virtual in MutexDirect.

release void MutexDirect::release(void) const; Description: Releases the mutex. It is an error to call this if the mutex was not already locked. This method is considered const so that you can lock and unlock const mutexes, mainly to allow thread-safe access to otherwise const data.
