+    @deprecated
+    The facilities provided by this header are deprecated.  True assertions
+    (that detect broken program logic) should use standard assert (which aborts
+    if an assertion fails, and is controlled by the standard NDEBUG macro).
+    Logging of warnings (e.g., about malformed input) and traces (e.g., about
+    steps taken while executing some protocol) should use the facilities
+    provided by (C++ only) sal/log.hxx.
+
+    Because the assertion macros (OSL_ASSERT, OSL_ENSURE, OSL_FAIL, OSL_PRECOND,
+    and OSL_POSTCOND) have been used for true assertions as well as for logged
+    warnings, they map to SAL_WARN instead of standard assert.  OSL_TRACE maps
+    to SAL_INFO.
+
+    The functions defined in this header are not intended to be used directly,
+    but through defined macros. The macros can be divided into three categories:
+    assertions, traces and other stuff .-) Their usability depends on the value
+    of OSL_DEBUG_LEVEL macro: assertions are only active if OSL_DEBUG_LEVEL is 1
+    or greater, traces if OSL_DEBUG_LEVEL is 2 or greater.
+
+    Traces:
+    OSL_TRACE(fmt, args...)
+        Prints trace message. The arguments have the same meaning as the
+        arguments of printf.

+/** A platform specific macro needed to make double-checked locking work.
+
+    See
+    <http://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html>
+    for a description of double-checked locking, why it is broken, and how it
+    can be fixed.  On platforms where it is necessary, this macro will expand
+    to some memory barrier instruction.  On many platforms, double-checked
+    locking works as it is, though, so on those platforms this macro will be
+    empty.  This is a macro instead of a (C++ inline) function to allow for
+    maximum performance in both C and C++.
+
+    If possible, use the rtl_Instance template instead of explicitly spelling
+    out the double-checked locking pattern.  There are few cases where you
+    will have to spell it out explicitly (e.g., the logic of a certain
+    instance of the pattern is too complex to be mapped to the template, or
+    some compiler refuses to compile a template instantiation due to internal
+    compiler errors), though, and you should always call this macro at the
+    right places then:
+
+    @code{.cpp}
+      static T * pInstance = 0;
+
+      T * p = pInstance;
+      if (!p)
+      {
+          Guard aGuard(aMutex);
+          p = pInstance;
+          if (!p)
+          {
+              p = ...;
+              OSL_DOUBLE_CHECKED_LOCKING_MEMORY_BARRIER();
+              pInstance = p;
+          }
+      }
+      else
+          OSL_DOUBLE_CHECKED_LOCKING_MEMORY_BARRIER();
+      return p;
+    @endcode
+
+    One extra advantage of this macro is that it makes it easier to find all
+    places where double-checked locking is used.

+/** @file
+
+Main goals and usage hints
+
+The main intention of this interface is to provide a universal portable and
+high performance access to file system functionality on any operating
+system.
+
+There are a few main goals:
+
+1. The path specifications always has to be absolute. Any usage of relative
+path specifications is forbidden. Exceptions are osl_getSystemPathFromFileURL,
+osl_getFileURLFromSystemPath and osl_getAbsoluteFileURL. Most operating
+systems provide a "Current Directory" per process. This is the reason why
+relative path specifications can cause problems in multithreading
+environments.
+
+2. Proprietary notations of file paths are not supported. Every path notation
+must the file URL specification. File URLs must be encoded in UTF8 and after
+that escaped. Although the URL parameter is a unicode string, the must
+contain only ASCII characters.
+
+3. The caller cannot get any information whether a file system is case
+sensitive, case preserving or not. The operating system implementation
+itself should determine if it can map case-insensitive paths. The case
+correct notation of a filename or file path is part of the "File Info". This
+case correct name can be used as a unique key if necessary.
+
+4. Obtaining information about files or volumes is controlled by a bitmask
+which specifies which fields are of interest. Due to performance reasons it
+is not recommended to obtain information which is not needed.  But if the
+operating system provides more information anyway the implementation can set
+more fields on output as were requested. It is in the responsibility of the
+caller to decide if they use this additional information or not. But they
+should do so to prevent further unnecessary calls if the information is
+already there.
+
+The input bitmask supports a flag osl_FileStatus_Mask_Validate which can be
+used to force retrieving uncached validated information. Setting this flag
+when calling osl_getFileStatus in combination with no other flag is a synonym
+for a "FileExists". This should only be done when processing a single file
+(i.e. before opening) and NEVER during enumeration of directory contents on
+any step of information processing. This would change the runtime behaviour
+from O(n) to O(n*n/2) on nearly every file system.  On Windows NT reading the
+contents of a directory with 7000 entries and getting full information about
+every file only takes 0.6 seconds. Specifying the flag
+osl_FileStatus_Mask_Validate for each entry will increase the time to 180
+seconds (!!!).
