-** nssilock.h - Instrumented locking functions for NSS
-**
-** Description:
-**    nssilock provides instrumentation for locks and monitors in
-**    the NSS libraries. The instrumentation, when enabled, causes
-**    each call to the instrumented function to record data about
-**    the call to an external file. The external file
-**    subsequently used to extract performance data and other
-**    statistical information about the operation of locks used in
-**    the nss library.
-**     
-**    To enable compilation with instrumentation, build NSS with 
-**    the compile time switch NEED_NSS_ILOCK defined.
-**
-**    say:  "gmake OS_CFLAGS+=-DNEED_NSS_ILOCK" at make time.
-**
-**    At runtime, to enable recording from nssilock, one or more
-**    environment variables must be set. For each nssILockType to
-**    be recorded, an environment variable of the form NSS_ILOCK_x
-**    must be set to 1. For example:
-**
-**       set NSS_ILOCK_Cert=1
-**
-**    nssilock uses PRLOG is used to record to trace data. The
-**    PRLogModule name associated with nssilock data is: "nssilock".
-**    To enable recording of nssilock data you will need to set the
-**    environment variable NSPR_LOG_MODULES to enable
-**    recording for the nssilock log module. Similarly, you will
-**    need to set the environment variable NSPR_LOG_FILE to specify
-**    the filename to receive the recorded data. See prlog.h for usage.
-**    Example:
-**
-**        export NSPR_LOG_MODULES=nssilock:6
-**        export NSPR_LOG_FILE=xxxLogfile
-**
-** Operation:
-**    nssilock wraps calls to NSPR's PZLock and PZMonitor functions
-**    with similarly named functions: PZ_NewLock(), etc. When NSS is
-**    built with lock instrumentation enabled, the PZ* functions are
-**    compiled into NSS; when lock instrumentation is disabled,
-**    calls to PZ* functions are directly mapped to PR* functions
-**    and the instrumentation arguments to the PZ* functions are
-**    compiled away.
-**
-**
-** File Format:
-**    The format of the external file is implementation
-**    dependent. Where NSPR's PR_LOG() function is used, the file
-**    contains data defined for PR_LOG() plus the data written by
-**    the wrapped function. On some platforms and under some
-**    circumstances, platform dependent logging or
-**    instrumentation probes may be used. In any case, the
-**    relevant data provided by the lock instrumentation is:
-**    
-**      lockType, func, address, duration, line, file [heldTime]
-** 
-**    where:
-**    
-**       lockType: a character representation of nssILockType for the
-**       call. e.g. ... "cert"
-**    
-**       func: the function doing the tracing. e.g. "NewLock"
-**    
-**       address: address of the instrumented lock or monitor
-**    
-**       duration: is how long was spent in the instrumented function,
-**       in PRIntervalTime "ticks".
-**    
-**       line: the line number within the calling function
-**    
-**       file: the file from which the call was made
-**    
-**       heldTime: how long the lock/monitor was held. field
-**       present only for PZ_Unlock() and PZ_ExitMonitor().
-**    
-** Design Notes:
-**    The design for lock instrumentation was influenced by the
-**    need to gather performance data on NSS 3.x. It is intended
-**    that the effort to modify NSS to use lock instrumentation
-**    be minimized. Existing calls to locking functions need only
-**    have their names changed to the instrumentation function
-**    names.
-**    
-** Private NSS Interface:
-**    nssilock.h defines a private interface for use by NSS.
-**    nssilock.h is experimental in nature and is subject to
-**    change or revocation without notice. ... Don't mess with
-**    it.
