/*
 * FILE
 * ttsafe.c - HDF5 threadsafe testing framework main file.
 *
 * REMARKS
 * General test wrapper for HDF5 library thread safety test programs
 *
 * DESIGN
 * Each test function should be implemented as function having no
 * parameters and returning void (i.e. no return value).  They should be put
 * into the list of InitTest() calls in main() below.  Functions which depend
 * on other functionality should be placed below the InitTest() call for the
 * base functionality testing.
 * Each test module should include ttsafe.h and define a unique set of
 * names for test files they create.
 *
 * BUGS/LIMITATIONS
 *
 * EXPORTED ROUTINES/VARIABLES:
 * Two variables are exported: num_errs, and Verbosity.
