verifies that the specified condition is fulfilled. If not, a message

is printed to ASSERT_STREAM if defined (defaulting to stderr if

undefined) and the program is terminated with an error code.
|
|
|
|
This macro has the following properties:
|
|
- The programmer specifies the expected condition, not the failure
|
|
condition. This simplifies thinking.
|
|
- The condition is tested always, regardless of compilation flags.
|
|
(Unlike the macro from <assert.h>.)
|
|
- On Unix platforms, the tester can debug the test program with a
|
|
debugger (provided core dumps are enabled: "ulimit -c unlimited").
|
|
- For the sake of platforms where no debugger is available (such as
|
|
some mingw systems), an error message is printed on the error
|
|
stream that includes the source location of the ASSERT invocation.
