Function: xmlCleanupThreads
void	xmlCleanupThreads		(void)
Packit Service a31ea6 
xmlCleanupThreads() is used to to cleanup all the thread related data of the libxml2 library once processing has ended. WARNING: if your application is multithreaded or has plugin support calling this may crash the application if another thread or a plugin is still using libxml2. It's sometimes very hard to guess if libxml2 is in use in the application, some libraries or plugins may use it without notice. In case of doubt abstain from calling this function or do it just before calling exit() to avoid leak reports from valgrind !
Packit Service a31ea6 
Function: xmlDllMain
int	xmlDllMain			(void * hinstDLL, 
					 unsigned long fdwReason, 
					 void * lpvReserved)
Packit Service a31ea6
Packit Service a31ea6 
<tt>hinstDLL</tt>:
<tt>fdwReason</tt>:
<tt>lpvReserved</tt>:
<tt>Returns</tt>:
Function: xmlFreeMutex
void	xmlFreeMutex			(xmlMutexPtr tok)
Packit Service a31ea6 
xmlFreeMutex() is used to reclaim resources associated with a libxml2 token struct.
Packit Service a31ea6 
<tt>tok</tt>:the simple mutex
Function: xmlFreeRMutex
void	xmlFreeRMutex			(xmlRMutexPtr tok)
Packit Service a31ea6 
xmlRFreeMutex() is used to reclaim resources associated with a reentrant mutex.
Packit Service a31ea6 
<tt>tok</tt>:the reentrant mutex
Function: xmlGetGlobalState
xmlGlobalStatePtr	xmlGetGlobalState	(void)
Packit Service a31ea6 
xmlGetGlobalState() is called to retrieve the global state for a thread.
Packit Service a31ea6 
<tt>Returns</tt>:the thread global state or NULL in case of error
Function: xmlGetThreadId
int	xmlGetThreadId			(void)
Packit Service a31ea6 
xmlGetThreadId() find the current thread ID number Note that this is likely to be broken on some platforms using pthreads as the specification doesn't mandate pthread_t to be an integer type
Packit Service a31ea6 
<tt>Returns</tt>:the current thread ID number
Function: xmlInitThreads
void	xmlInitThreads			(void)
Packit Service a31ea6 
xmlInitThreads() is used to to initialize all the thread related data of the libxml2 library.
Packit Service a31ea6 
Function: xmlIsMainThread
int	xmlIsMainThread			(void)
Packit Service a31ea6 
xmlIsMainThread() check whether the current thread is the main thread.
Packit Service a31ea6 
<tt>Returns</tt>:1 if the current thread is the main thread, 0 otherwise
Function: xmlLockLibrary
void	xmlLockLibrary			(void)
Packit Service a31ea6 
xmlLockLibrary() is used to take out a re-entrant lock on the libxml2 library.
Packit Service a31ea6 
Function: xmlMutexLock
void	xmlMutexLock			(xmlMutexPtr tok)
Packit Service a31ea6 
xmlMutexLock() is used to lock a libxml2 token.
Packit Service a31ea6 
<tt>tok</tt>:the simple mutex
Function: xmlMutexUnlock
void	xmlMutexUnlock			(xmlMutexPtr tok)
Packit Service a31ea6 
xmlMutexUnlock() is used to unlock a libxml2 token.
Packit Service a31ea6 
<tt>tok</tt>:the simple mutex
Function: xmlNewMutex
xmlMutexPtr	xmlNewMutex		(void)
Packit Service a31ea6 
xmlNewMutex() is used to allocate a libxml2 token struct for use in synchronizing access to data.
Packit Service a31ea6 
<tt>Returns</tt>:a new simple mutex pointer or NULL in case of error
Function: xmlNewRMutex
xmlRMutexPtr	xmlNewRMutex		(void)
Packit Service a31ea6 
xmlRNewMutex() is used to allocate a reentrant mutex for use in synchronizing access to data. token_r is a re-entrant lock and thus useful for synchronizing access to data structures that may be manipulated in a recursive fashion.
Packit Service a31ea6 
<tt>Returns</tt>:the new reentrant mutex pointer or NULL in case of error
Function: xmlRMutexLock
void	xmlRMutexLock			(xmlRMutexPtr tok)
Packit Service a31ea6 
xmlRMutexLock() is used to lock a libxml2 token_r.
Packit Service a31ea6 
<tt>tok</tt>:the reentrant mutex
Function: xmlRMutexUnlock
void	xmlRMutexUnlock			(xmlRMutexPtr tok)
Packit Service a31ea6 
xmlRMutexUnlock() is used to unlock a libxml2 token_r.
Packit Service a31ea6 
<tt>tok</tt>:the reentrant mutex
Function: xmlUnlockLibrary
void	xmlUnlockLibrary		(void)
Packit Service a31ea6 
xmlUnlockLibrary() is used to release a re-entrant lock on the libxml2 library.
