+/** @file
+ Provides simple diagnostic support.
+
+ @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.
