36 * ascDynaLoad.[ch] has several different platform-dependent
37 * implementations. This test function only tests the platform it
38 * is being run on. At present, testing is not implemented for all
39 * ASCEND platforms.
40 *
41 * This test function attempts to open and execute a shared library
42 * whose path is defined in variable shlib_name. Modify this variable
43 * for the shared library you want to use. Minimally, the shared
44 * library must provide the following public symbols:
45 *
46 * - init function, [int (*)(void)], returns -5.
47 * - isInitialized function, [int (*)(void)], returns TRUE if init()
48 * has been called, FALSE if cleanup or nothing has
49 * been called.
50 * - cleanup function, [void (*)(void)], no return.
51 * - value data [int] == FALSE initially, TRUE after init() has
52 * been called, FALSE after cleanup() has been called.
