Each time a bug is fixed, a * test case is written to prove the fix and ensure * that later changes to the code don't reintroduce the * same error. The number of test cases is slowly growing * and therefore so is the code reliability. * * Compliance: * See the file ANNOUNCE for the list of implemented * and not-implemented routines and defined options. * Of course, these are all defined is this file as well. * * Web site: * The source code and other information about this library * are available from * * http://sources.redhat.com/pthreads-win32/ * * ------------------------------------------------------------- */ #include #include #include /* * Boolean values to make us independent of system includes. */ enum { PTE_FALSE = 0, PTE_TRUE = (!
