// 1) VERIFY(), via _GLIBCXX_ASSERT, from Brent Verner <brent@rcfile.org>.

// This file is included in the various testsuite programs to provide

|
|
// 2) set_memory_limits()
|
|
// set_memory_limits() uses setrlimit() to restrict dynamic memory
|
|
// allocation. We provide a default memory limit if none is passed by the
|
|
// calling application. The argument to set_memory_limits() is the
|
|
// limit in megabytes (a floating-point number). If _GLIBCXX_RES_LIMITS is
|
|
// not #defined before including this header, then no limiting is attempted.
|
|
//
|
|
// 3) counter
|
|
// This is a POD with a static data member, gnu_counting_struct::count,
|
|
// which starts at zero, increments on instance construction, and decrements
|
|
// on instance destruction. "assert_count(n)" can be called to VERIFY()
|
|
// that the count equals N.
|
|
//
|
|
// 4) copy_tracker, from Stephen M. Webb <stephen@bregmasoft.com>.
|
|
// A class with nontrivial ctor/dtor that provides the ability to track the
|
|
// number of copy ctors and dtors, and will throw on demand during copy.
