/** provides simple diagnostic support
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.
Assertions (cond is bool, msg is char*):
OSL_ASSERT(cond)
If cond is false, reports an error.
OSL_ENSURE(cond, msg)
If cond is false, reports an error with message msg.
OSL_FAIL(msg)
Reports an error with message msg unconditionally.
OSL_PRECOND(cond, msg)
OSL_POSTCOND(cond, msg)
These two are functionally equivalent to OSL_ENSURE(cond, msg). They are
intended to be used for checking pre- and postconditions of functions.
Traces:
OSL_TRACE(fmt, args...)
Prints trace message. The arguments have the same meaning as the
arguments of printf.
Other:
OSL_VERIFY(expr)
Evaluates the expression and if it is false, reports an error. The
expression is evaluated once without regard of the value of
OSL_DEBUG_LEVEL.
Example:
void extractBool(Any const& rAny, bool& rBool)
{
OSL_VERIFY(rAny >>= rBool);
}
OSL_DEBUG_ONLY(expr)
