/**@file sofia-sip/tstdef.h Macros for unit tests
 *
 * The macros defined here can be used by unit test programs. When a test
 * fails, the TEST macros print the offending file name and line number.
 * They use format that is accepted by Emacs and other fine editors so you
 * can directly go to the source code of the failed test with next-error.
 *
 * @note There is no protection agains multiple inclusion.

 *
 * @par Example Program
 *
 * You should define the macro TSTFLAGS to a int variable possibly
 * containing a flag #tst_verbatim. As a convention, the int variable should
 * be set when your test program is run with @c -v or @c --verbatim command
 * line option. If the (TSTFLAGS & tst_verbatim) is true, the test macros
 * log the test before executing it and the result of successful tests, too.
 *
 * You should typedef longlong to integer type at least 64 bit wide before
 * including <sofia-sip/tstdef.h>, too.
 *
 * As an example, we provide a test program making sure that inet_ntop() and
 * inet_pton() behave as expected and that we can create UDP/IPv4 sockets
 * with @b su library:
 *
 * @code
 * #include "config.h"
 *
 * #include <stdio.h>
 * #include <limits.h>
 *
 * #include <sofia-sip/su.h>
 *
 * #define TSTFLAGS tstflags
 *
 * #include <stdlib.h>
 * #include <sofia-sip/tstdef.h>
 *
 * static int tstflags = 0;
 *
 * void usage(void)
 * {
 *   fprintf(stderr, "usage: %s [-v|--verbatim]\n", name);
 *   exit(2);
 * }
 *
 * static int socket_test(void);
 *
 * int main(int argc, char *argv[])
 * {
 *   int retval = 0, i;
 *
 *   for (i = 1; argv[i]; i++) {
 *     if (strcmp(argv[i], "-v") == 0 || strcmp(argv[i], "--verbatim") == 0)
 *       tstflags |= tst_verbatim;
 *     else
 *       usage();
 *   }
 *
 *   retval |= socket_test(); fflush(stdout);
 *
 *   return retval;
 * }
 *
 * double max_bandwidth()
 *
 * int socket_test(void)
 * {
 *   su_socket_t s;
 *   char buf[64];
 *   unsigned long localhost = htonl(0x7f000001);
 *   unsigned long addr;
 *
 *   BEGIN();
 *
 *   // Check inet_ntop() return value (Tests equality of integral values)
 *   TEST(inet_ntop(AF_INET, &localhost, buf, sizeof buf), buf);
 *
 *   // Check inet_ntop() result (Tests equality of strings)
 *   TEST_S(buf, "127.0.0.1");
 *
 *   // Check inet_pton() argument validation (Tests equality of ints)
 *   TEST(inet_pton(0, buf, &addr), -1);
 *
 *   // Check inet_pton() return value (Tests for true value (non-zero))
 *   TEST_1(inet_pton(AF_INET, buf, &addr) > 0);
 *
 *   // Check inet_pton() result (Tests equality of memory areas)
 *   TEST_M(&addr, &localhost, sizeof(addr));
 *
 *   // Test to create UDP socket (Test for true value)
 *   TEST_1((s = su_socket(AF_INET, SOCK_DGRAM, 0)) != INVALID_SOCKET);
 *
 *   // Check max bandwidth
 *   TEST_D(max_bandwidth(), DBL_MAX);
