+ The TEST_FUNCTION expression should have a type of 'int' and should
+ return 0 to indicate a passing test, 1 to indicate a failing test,
+ or 77 to indicate an unsupported test. Other result values could be
+ used to indicate a failing test, but the result of the expression
+ is passed to exit and exit only returns the lower 8 bits of its input.
+ A non-zero return with some values could cause a test to incorrectly
+ be considered passing when it really failed. For this reason the
+ expression should always return 0, 1, or 77.
+
+ The test function may print out diagnostic or warning messages as well
+ as messages about failures. These messages should be printed to stdout
+ and not stderr so that the output is properly ordered with respect to
+ the rest of the glibc testsuite run output. */
