The {\bf Read\-Lock}{\rm (p.\,\pageref{classost_1_1_read_lock})} class is used to protect a section of code through a {\bf Thread\-Lock}{\rm (p.\,\pageref{classost_1_1_thread_lock})} for \char`\"{}read\char`\"{} access to the member function.Read mode automatic locker for protected access.

\subsection{Detailed Description}
The {\bf Read\-Lock}{\rm (p.\,\pageref{classost_1_1_read_lock})} class is used to protect a section of code through a {\bf Thread\-Lock}{\rm (p.\,\pageref{classost_1_1_thread_lock})} for \char`\"{}read\char`\"{} access to the member function.Read mode automatic locker for protected access. 

The {\bf Thread\-Lock}{\rm (p.\,\pageref{classost_1_1_thread_lock})} is automatically released when the object falls out of scope.

A common use is

void func\_\-to\_\-protect() \{ {\bf Read\-Lock}{\rm (p.\,\pageref{classost_1_1_read_lock})} lock(threadlock); ... operation ... \}

NOTE: do not declare variable as \char`\"{}Read\-Lock (threadlock)\char`\"{}, the mutex will be released at statement end.
